Elizabeth R. ★★★★★

Swapped out my old reference sphere for this f/1.0, and the difference at 3.39 µm is immediately noticeable—the fringe contrast on my test parts is much cleaner. It’s a solid 3-inch optic that feels precision-ground, no tweaking needed right out of the box.

Violet ★★★★★

Installing this on my interferometer was straightforward, and the optic sits perfectly flush with no wobble. The 3-inch diameter gives plenty of coverage for my test pieces, and the infrared transmission is exactly what I needed.

Emma ★★★★★

The 3.39 µm spec was exactly what I needed for our mid-IR setup, and the f/1.0 cone angle gives a much wider test aperture than the f/1.5 we were borrowing before. Interferograms came back clean right out of the case, no surprises.
