Amelia Q. ★★★★★

I was pleasantly surprised by how flat these mirrors are straight out of the box—the fused silica substrate feels rock-solid compared to standard glass optics. They reflect my UV laser cleanly at 355nm with no visible distortion, and the 25.4mm size fits perfectly into my mount. Exactly what I neede

Stella W. ★★★★★

The UV-enhanced coating really holds up—I tested it across a UV range and the reflectivity stayed consistently above 90%, just as specified. The 50.8mm fused silica piece arrived with a flawless polish, no scratches or defects to fuss over.

Victoria X. ★★★★★

The fused silica substrate on these is noticeably flatter than the borosilicate ones I used before, and my beam stays tight across the whole 250-450nm range. Polished edges look clean under a loupe too.
