    Avery Q. ★★★★★

    The 5 arc second parallelism spec held up perfectly when I tested it on my autocollimator; the surfaces are so clean I didn't even need to re-clean them before mounting. This is the third λ/10 window I've bought for my lab and the consistency is reassuring.

    Riley ★★★★★

    Swapped the λ/10 version into my interferometer setup and the fringe pattern cleaned up immediately — way flatter than the generic windows I'd been fighting with. Edge finish is clean too, no chips or sleeks out of the box.

    Brian ★★★★★

    The λ/10 flatness on these windows is incredible for the price—my interferometer readings were spot on. Even the 5 arc second parallelism held up perfectly in my setup.
