Sebastian ★★★★★

Set it up on an interferometer this morning and the fringe quality is outstanding—easily the cleanest 1/20 wave reference I’ve worked with. The F/1.1 aperture lets me test fast optics without any clipping issues.

Edward P. ★★★★★

I’m really impressed with how clean the 1/20 wave surface is on this 6” sphere—the fringes were dead stable as soon as I got it aligned. For the price, getting a transmission sphere with this kind of figure quality for an F/1.1 aperture feels like a steal. It’s already become our go‑to for calibrati

Riley ★★★★★

Swapped this in on our F/1.1 interferometer setup and the fringe contrast immediately looked cleaner across the full aperture. The 6" clear aperture covers our larger flats without stitching, which saves a ton of time. Easily the best transmission sphere I've used at this price point.
