Anyone have an idea what this gas laser optical board was used for?

Will be awhile until I can do anything with it, it came in the mail to my home in Alaska, but I have not been able to see it yet due to being on the other side of the planet and not coming back for months.

If I were you I would be emailing laboratories near your home and asking them if they can test your interferometer. Maybe you could get an RoHS certificate, but even if you can't it would still be cool to see how it works. You can do cool things like measure the speed of light and measure gravity waves.

I wonder if any of these parts can be used for a double slit experiment with the right laser source and camera, I won't be tearing them down until all other usefulness is first explored.
