Referentiespiegels voor differentiële vlakspiegel-interferometer (DPMI)

Installing these into our DPMI setup was seamless — the mounting threads lined up perfectly with our existing hardware. The polished edge bevel makes handling them without fear of chipping much easier than our old mirrors.

The flatness tolerance on these mirrors is tighter than my old set, which cleaned up my interference fringe patterns immediately. Works perfectly with the DPMI setup I have, and switching configurations is straightforward.

Swapped between the two mounting styles for our DPMI rig and both aligned cleanly out of the box, which saved me a good hour of fiddling. The surface quality on these references is noticeably consistent across the set, and that’s exactly what I needed for repeatable differential measurements.
