Michelson Interferometer by Holmarc Opto Mechatronics Private Limited

Michelson interferometer is a widely used instrument for measuring the wavelength of light, refractive index of transparent materials etc. The interferometer Model HO-ED-INT-06 is designed and constructed in modular fashion. Students can assemble the interferometer out of individual modules by fixing them on optical breadboard. All components required for such assembly, including screws and allen keys, are supplied with this package.

The beam-splitter is designed to reflect 50% of the incident light and transmit the other 50%. The incident beam therefore is split into two beams; one beam is reflected towards mirror M1, the other is transmitted toward mirror M2. Both mirror reflects the beams back toward the beam-splitter. Half the light from M1 is transmitted through the beam-splitter to the screen and half the light from M2 is reflected by the beam-splitter to the screen.

Experiment ListStandardization of meter. (To find the proportionality constant of the lever system)Determination of wavelength of monochromatic light. Diode laser with wavelength of 650nm (Green) & 532nm (Red) are usedMeasurement of refractive index of transparent materialsTo study the change of refractive index of air with change in pressure and determine the refractive index of air.
