55968 Michelson interferometer is a unique setup for the demonstration of interferometry. Michelson interferometer was used in famous Michelson -Morley experiment to show the constancy of speed of light and evidence of special relativity. The interference pattern is observed by splitting a beam of light into two paths, bouncing the beams back by mirrors and recombining them. The different paths may be of different lengths or composed of different materials to create alternating interference fringes. 55968 has compact design and is very easy to operate. The setup can be used with different types of sources like He-Ne LASER, Diode LASER.

Features
