The Jamin  Interferometer       
This interferometer is designed to demonstrate interference pictures in a lecture room. To make up this device we used glass template PI that is applied in metal working plants to verify flatness. One plate was cut in half for two mirrors to be fabricated.

Great advantage of this device is that it works with the white light. Bright, colorful interference picture can be seen on the screen. Picture size is 50 cm in diameter. We show a fringe width changes at the rapid changing red and blue filters. Small distance between light beams in this interferometer is very convenient to show the experiment by FresnelArago. It is possible to estimate the thickness of a soapy film, putting it in one beam of the interferometer.
