    • Dipole Meter is an adaptable instrument that is used for measuring the dielectric constant of non-polar liquids. In the equipments a particular circuit has been developed for audio oscillator that produces stabilized wave. In this experiment dielectric cell is standardized using reference liquid having known dielectric constant by immersing the dielectric cell assembly in to reference Liquid. Then experimental liquid whose dielectric constant has to be determined is taken and assembly is immersed into liquid, resulting in change in oscillation frequency. From resulting shift, capacitance of cell in unknown liquid is calculated (CX). Dielectric Constant of unknown liquid is calculated using relation:
    • Where Capacitance of Air,Capacitance of standard liquid, Capacitance of test liquid and dielectric constant of standard liquid solution of polar molecule having molecular wt. with non-polar solvent having molecular wt. in different concentrations, is considered. Molar Polarization of the mixture is obtained by relation
    • Where k is dielectric constant of the solution having mole fraction of polar molecule and mole fraction of non polar solvent and is the density of the mixture.
    • A graph between and is obtained The dipole moment is calculated using relation, Where T is absolute temperature, is molar polarization of non-polar liquid and is molar polarisation of non polar liquid.

              The Michelson interferometer is an optical instrument of high precision and versatility. It generally is used in investigations that involve small changes in optical path lengths. With the Michelson interferometer, one can produce circular and straight-line fringes of both monochromatic light and white light. One can use these fringes to make an accurate comparison of wavelengths, measure the refractive index of gases and transparent solids, and determine small changes in length quite precisely. The instrument can be used as a stable mode selecting resonator element in laser cavities as well. The Michelson interferometer is perhaps the best known and most basic in a family of interferometers which includes the Fabry-Perot interferometer, the Twyman-Green interferometer and the Mach-Zehnder interferometer

              The PRISM Make Michelson Interferometer is constructed on a Machined Steel Base. High precision movable-mirror with smooth fine movement of 0.6 microns facilitates fringe counting.

              You can upgrade by adding few parts to work as Fabry Perot Interferometer & Twyman Green Interferometer.

                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.

                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 are 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 square ness 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 with the junction of its reflecting faces nominally central with 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 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.

                  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.
