V-TECH India offers two different types of Monochromatic Light source. Monochromatic Light Source are used in Calibration labs for inspection of Micrometer Anvils & Mechanical Seals, Pump Valves and various other Automotive Parts manufacturers. V-TECH India Monochromatic Light Source provides highly diffused Sodium light for use in testing flatness of flat parts with Master Optical Flats. Sodium Vapour Light is directed on to the component under inspection through a plane acrylic sheet with a straight line marked on its face. It produces Excellent Contrast Fringes.

Model VT-01:
  • This is used when the Optical Flat is less than 150 mm diameter. The Optical Flat is placed over the polished part under inspection. The light bands are viewed over the Optical Flat from above

Model VT-02:
  • The part to be inspected is placed over the Optical Flat and the light bands are viewed from beneath after reflection from a mirror. This Type Monochromatic Light Source is used when the part under inspection is thin and of large diameter. If an Optical Flat of large diameter is to be placed on such thin parts there would be deformation of fringes due to the weight of large size Optical Flat. To avoid this the part to be inspected is placed over the Optical flat and the fringes are viewed after reflection from a mirror placed below.
  • The Master surface of the Optical Flat face upwards and the test surface face downwards and are in contact to view the light bands. MLS-02 is suitable for use with 200 mm diameter Optical Flat. On request MLS to suit Optical Flats larger than 200 mm diameter is manufactured against specific Order.

      Pure alkali halide crystals are transparent throughout the visible region of the spectrum. The crystals

      may be colored in a number of ways

      (1) by the introduction of chemical impurities

      (2) by introducing an excess of the metal ion

      (3) by X-ray, g-ray, neutron and electron bombardment

      (4) by electrolysis

      Colour centres produced by irradiation with X-rays

      When a X-ray quantum passes through an ionic crystal, it will usually give rise to a fast photo-electron with an energy of the same order as that of the incident quantum. Such electrons, because of their small mass, do not have sufficient momentum to displace ions and therefore loose their energy in

      producing free electrons, holes, excitons and phonons. Evidently these while moving near the vacancies form trapped electrons as well as trapped holes. The trapped-electron or trapped-hole centres so formed can be destroyed (bleached) by illuminating the crystal with light of the appropriate wavelength or warming it.

      Thermoluminescence

      Important information about the colour centres can be obtained by measuring the changes that occur when a coloured crystal is gradually heated. As the temperature is raised electrons and holes escape from their

      traps at an increasing rate. The freed charges can recombine with each other or with other defects and give out luminescence by recombination.

      The resulting thermoluminescence or ‘glow’ reaches maximum and then decreases to zero as the supply of trapped electrons or holes becomes exhausted. The plot of luminescence intensity verses temperature, taken

      at a constant heating rate, is called the ‘glow curve’. It may contain one or many glow peaks, depending upon whether there are one or several different kinds of traps.

      From the glow curve one determine the trap depth; the deeper the trap, the higher the temperature of the glow peak. A correlation between the temperature at which thermoluminescence occurs and the temperature at which particular band bleach can give valuable information about specific

      centres. Typical results obtained from this set-up for

      KCl crystal are shown in figure.

      The experiment consists of the following

        A special Micrometer Anvil Checker designed and developed by Prisms India replaces the use of many sets of Optical Parallel or Gauge Blocks/Slip Gauges to cover a wide range of Micrometers.

        The principle of working:

        The light from the Autocollimator is divided into two parts by reflection at the faces of a 90 deg prism so that each part is directed towards one of the gauging tips, the polished surface of which acts as a suitable reflector. The angle between the reflecting faces of the prism is precisely 90 degrees so that the two reflected beams are collinear. The light beam is reflected at the anvil surfaces and re-enter the instrument after a second reflection from the 90 degrees prism. Each beam forms a reflected image of the scale, and if the anvils are parallel these images coincide; otherwise the departure from parallelism is readily measured by reading the separation of the images against the fixed scale. Moreover, the squareness of the face of the micrometer spindle to the axis of rotation can also be checked, by measuring any displacement of the appropriate image as the spindle is rotated.

        The prism is placed at the junction of its reflecting faces nominally central to the instrument object glass, and with the faces in line with the micrometer anvils. Displacement or tilt of the prism has no effect upon measurement, but the rotation of the prism (so that its edge is inclined to the anvils) will produce a separation of the reflected images at right angles to the micrometer axis. The prism must be adjusted rotationally until this separation is a minimum. Any error in the 90 degrees angle between the reflecting faces is doubled in its effect upon the reflected images since two reflections occur at each face.

        The main advantage of this instrument is that all sizes of Micrometer ranging from 25 mm to 300 mm could be inspected for parallelism, whereas you need to have gauge blocks or Optical parallel for every size of Micrometer.

        The graduated reticule of the Instrument (VTC-01) reads 1 division = 0.923 microns (say 1 micron) Parallelism error of the spindle and the Anvil of the Micrometer.

        Another model (VTC-02). is also available with least count of 0.739 microns.

        Moreover, this Instrument with Micrometer readout could also be used as an Autocollimator for straightness, parallelism, squareness, Rotary table calibration measurements.
        VTC-01 – 3 arc secs/Micrometer Div , Range 3 meters, 14.5 microns per meter,
        VTC-02 – 1 arc sec/Micrometer Div, Range 4.5 meters, 4.83 microns per meter.

              These instruments are used in contact angle measurement, surface free energy analysis, and surface or interfacial tension measurement.The V TECH (VT) series contact angle meters have a range of systems starting from DMs-200, which is the basic model, to the most sophisticated VT-701.The VT-200 model is used to determine contact angle using the sessile drop method in static mode.

              From model VT-CE1, all instruments can determine contact angle using the sessile drop method in static mode as well as in dynamic mode. The surface tension of a liquid sample can also be determined. The robust FAMACS software ensures that the system can also give dynamic contact sessile drop method,extension/contraction method, surface or interfacial tension of liquids with pendant drop method,sliding method, and dynamic sliding method. This is the most automatic model and even stage movement and droplet deposition can be controlled through the PC.

               

              Optional accessories are numerous to choose from including computer-controlled dispenser, sliding method, temperature control of stage, temperature control of dispenser, and high speed camera.With the surface free energy software, the solid surface free energies and their components from the results of contact angle with different liquids can be measured.If surface free energy is the main analysis, then there is also an option called surface energy kit which consists of five kinds of probe liquids and proper needles.

               

              Applications

              The contact angle meter has application in the pharma field, where the wettability of powders can be studied. The contact angle measurement gives remarkable data on wettability and thus pharma companies can use this tool in their analytical research and development.

                Four Probe Method

                Resistivity of Semiconductor by Four Probe Method at different temperatures

                and determination of the Band-gap

                The Four Probe Method is one of the standard and most widely used method for the measurement of resistivity of semiconductors. The experimental arrangement is illustrated. In its useful form, the four probes are collinear. The error due to contact resistance, which is specially serious in the electrical measurement on semiconductors, is avoided by the use of two extra contacts (probes) between the current contacts. In this arrangement the contact resistance may all be high compare to the sample

                resistance, but as long as the resistance of the sample and contact resistances are small compared with the effective resistance of the voltage measuring device (potentiometer, electrometer or electronic voltmeter), the measured value will remain unaffected. Because of pressure contacts, the arrangement is also specially useful for quick measurement on different samples or sampling different parts of the same sample.

                Description of the experimental set-up

                1. Probes Arrangement

                It has four individually spring loaded probes. The probes are collinear and equally spaced. The

                probes are mounted in a teflon bush, which ensure a good electrical insulation between the probes.

                A teflon spacer near the tips is also provided to keep the probes at equal distance. The whole – arrangement is mounted on a suitable stand and leads are provided for the voltage measurement.

                2. Sample

                Germanium crystal in the form of a chip

                3. Oven

                It is a small oven for the variation of temperature of the crystal from the room temperature to about

                200°C (max.)

                4. Four Probe Set-up, DFP-02

                The set-up consists of three units in the same cabinet.

                (i) Multirange Digital Voltmeter

                In this unit, intersil 3½ digit single chip A/D Converter ICL 7107 has been used. It has high accuracy like auto zero to less than 10μV, zero drift of less than 1μV/ °C, input bias current of 10pA max. and roll-over error of less than one count. Since the use of internal reference causes the degradation in performance due to internal heating, an external reference has been used.

                Display 3½ digit, 7 segment LED (12.5mm height) with auto polarity and decimal indication Overload Indicator Sign of 1 on the left & blanking of other digits

                (ii) Constant Current Generator

                It is an IC regulated current generator to provide a constant current to the outer probes irrespective of the changing resistance of the sample due to change in temperatures. The basic scheme is to use the feedback principle to limit the load current of the supply to preset maximum value. Variations in the current are achieved by a potentiometer included for that purpose. The supply is a highly regulated and practically ripple free d.c. source. The current is measured by the digital panel meter.

                SPECIFICATIONS

                Line Regulation:

                0.05% for 10% changes

                (iii) Oven Power Supply Suitable voltage for the oven is obtained through a step down transformer with a provision for low and high rates of heating. A glowing LED indicates, when the oven power supply is ‘ON’. The experimental set-upis complete in all respect

                Typical results obtained from this set-up are shown in the figure.

                FeaturesCorrosion Resistance

                NUNES Crackness Apparatus consists of a clamp device, which rigidly holds one end of the test piece. A mandrel of the desired diameter and a roller of diameter 25mm make contact with the flesh and the grain surface respectively of the middle portion of the test piece, across its full width. The axes of both the mandrel are fixed relative to the clamp, the axel of the roller is attached to a handle pivoted at the axis of the mandrel. It consists of a horizontal base plate to which is rigidly attached a shouldered spigot whose narrow part has the diameter of the smallest mandrel. The circular hole in the handle fits over, which thus acts as a pivot. A mandrel of the desired diameter fits. A roller of diameter 25mm is carried on a vertical axel fixed to the handle in such a way that its distance from the circular hole may be set at any value desired. The test piece clamp is attached to a slotted strip, which allows its position relative to the base plate to be varied. All the mandrels are made of stainless steel and the other parts are either painted or chrome plated to give a corrosion resistance long life.

                    Introduction

                    This experiment aims at measuring the charge of an electron and is perhaps the most basic of allatomic physics or modern physics laboratory experiments. It won Millikan the Nobal Prize in the year 1923.

                    The experiment depends on the ability to control, measure and balance very small force of the order 10-14N. The set-up consists of two horizontal parallel plates separated by about 5mm. The upper plate has a small hole through which microscopic oil droplets are sprayed in between the two plates with the help of an atomizer which is like a common perfume sprayer. These droplets get charged due to the frictional force during spraying. The free fall of these droplets in the space between the plates is observed in the gravitational field. A measurement of the velocity of fall along with the use of Stokes law leads to the calculation of the mass of the droplets and their radii if the oil density is known. These are of the order of 10-15kg and 10-6m respectively. By applying a potential difference between the plates, a uniform electric field is produced in the space between the plates. A measurement of the velocity of the negatively charged droplets rising in the electric field allows a calculation of the electric force on the droplets and hence the charge carried by them. In the experiment the droplets which rise and fall slowly are selected as they are expected to have a fairly small charge. These droplets are made to rise and fall several times. The repetitions of measurement of the velocities of rise and fall reduce the random error of their means. A fairly large number of droplets are observed and their charges are calculated. The analysis of the data on the total charge carried by the droplets shows that these total charges are integral multiples of a certain smallest charge which is the charge of an electron. This result also shows that the charge is quantized.The measurement of the charge on the electron can lead to the calculation of Avogadro’s number. The charge F (the Faraday) required to electro-deposit one gram equivalent of an element on an electrode during electrolysis is equal to the charge of the electron multiplied by the number of molecules in a mole. The Faraday has been found to be F = 9.625×10 7 coulombs per kilogram equivalent weight. Hence Avogadro’s number N = F/e.

                    Introduction

                    Regular arrangement of atoms in molecules and extended solids is very common. In crystalline solids the atoms are arranged in repeating three-dimensional arrays or lattices. Information regarding atomic bond distances and angles is fundamental to understanding the chemical and physical properties of materials. Since atomic dimensions are of the order of angstroms (10 m), unraveling the relative atomic positions of a solid requires a physical technique that operates on a similar spatial scale, Diffraction experiments involving X-ray, electron and neutron sources have therefore played a very crucial role in unraveling these structures. The significance of these experiments in science and engineering courses has been recognized. However, the cost of the equipment and the hazards associated with these experiments have made them very difficult to be

                    integrated and included in a teaching laboratory setting. The present set-up overcomes these limitations. An increase in scale by thousands from short wavelengths of X-rays to the long wavelengths of visible light, and by hundreds of thousands from an array of atoms in a crystal or an extended solid to an array of dots, allows us to replicate the basic features of a structural determination experiment in a teaching laboratory.

                    In place of Bragg diffraction whose results are to be simulated, we use Fraunhofer diffraction. Visible laser light passes through an array of scattering centers (dots) on a 35 mm slide. The diffraction pattern is viewed at

                    what is effectively infinite distance (a meter or so). This arrangement is capable of illustrating many of the essential features of the standard X-ray experiment. Mathematically, the equations for Fraunhofer and Bragg diffraction have a similar functional dependence on the interatomic distance, wavelength and the scattering angle. The symmetry of the diffraction pattern is same as the symmetry of the lattice causing the diffraction.

                    The central piece of the set-up is a slide (transparency) with eight (A-H) different arrangements of scattering

                    centers (dots) on different portions of the slide (Figure 3). The examples presented here serve to illustrate how the spacings, symmetries, spot intensities and systematic absences in a diffraction pattern are related to the lattice from which it is derived. Although these are two-dimensional lattices, they mimic what would be observed for diffraction from particular three-dimensional structures that are viewed in projection perpendicular to a face.

                    VT-03 Leak Tester is designed for the examination of the airproof property of packages, containers, bags, pipes. VT-03 package air proof tester is widely used in food, beverage, pharmaceutical, daily chemical, electrical and electronic industries, etc. VT-03 Leakage Tester complies with V-TECH D3078 and GB/T 15171 standards. The leak detection system is composed of the mainframe and the vacuum chamber. A test sample is placed in a vacuum chamber with water and the air above water level is evacuated by a venturi vacuum ejector. A great pressure difference is created inside and outside the sample and any slight leakage can be observed and identified when the sample is inflated.
