Michelson Interferometer

To determine the wavelength of Sodium Light/Laser Light using Michelson Interferometer with arrangement to micro measure Highly polished plane slabs placed parallel at 45 and mirrors are placed right angle. Laser light with power supply fitted. Fringes formed are easily visible on wall or paper.Precisely developed with all perfect Optical, Mechanical components in our Research Laboratory, mainly used to find the wave length of monochromatic light or the calibration of scales and the standard experiments.
