Julian ★★★★★ Oct 18, 2026

The f/4.0 aperture paired perfectly with our existing setup, and the 1/20th wave accuracy at 3.39 µm showed up in cleaner fringes than I expected. Mounting was straightforward, and it held alignment through a full afternoon of testing.

Penelope J. ★★★★★ Oct 14, 2026

Swapped this onto our interferometer for a 3.39 μm source and the fringe contrast cleaned up immediately, way tighter than the f/4.0 setup we were running before. Alignment took a bit of fiddling, but once it locked in the wavefront looked flat across the whole aperture.

Natalie ★★★★★ Oct 13, 2026

The 1/20th wave spec at 3.39 μm is no joke — fringes stayed clean and straight across the whole aperture. F/4.0 worked well for our beam expansion setup. Took a few days to arrive, but the packaging was solid.
