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.

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.

Roller Diameter25 mm
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.

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.

 

(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.

Separating Calorimeter:
  • It consists of two concentric chambers, the inner chamber and the outer chamber, which communicates with each other through an opening at the top
  • As the steam discharges through the metal basket, which has a large number of holes
  • The water particles due to their heavier momentum get separated from the steam and collect in the chamber
  • The comparatively dry steam in the inner chamber moves up and than down aging through the annular space between the two chambers and enters the Throttling Calorimeter

Throttling Calorimeter:
  • It consists a narrow throat (Orifice)
  • Pressure and temperature are measured by pressure gauge and thermometer
  • The steam after throttling process passes through the heat exchanger and condensate is collected
  • There is no need of boiler.

Scope of Experimentations:
  • To find the dryness fraction of steam
