yes we used a flat with an interference pattern to measure consistency of the concavity - that it would reveal inconsistency causing lack of sameness in the pattern. I recall my piece turned out well, luckily - but also recall how the method was so precise that you could place your fingertips on the glass for a few seconds and the "bumps" in the pattern would appear where the heat from the fingers caused the surface to expand
Sounds like you should get back some of the instrumentation or express it in building some items in order to express your interest
I did that optics stuff 30 years ago so it has been awhile for me too
