We produce an interferometer with your specified request sizes and laser light sources.



The light, that came out from the light source S, is changed to parallel light at the collimator lens L1, and it is divided 2 luminous fluxes by the half mirror HM1.
Reflected light is reflected by the mirror M1, and it runs through the half mirror HM2 and the lens L2 to reach the P.
On the other hand, the light which was transmitted from the half mirror HM1 is reflected to both the mirror M2 and the half mirror HM2, and it runs through the lens L2 and reaches P.
These 4 reflecting surfaces are almost parallel, and the corners of the parallelogram are arranged to be in the center of the reflection.
