雙凸透鏡，S1-UV等級熔融石英

The edges came perfectly beveled and fine ground, so mounting them into my setup took no extra cleanup work. For finite conjugate imaging across the UV range, these have held up flawlessly through repeated use.

I picked these up for finite conjugate imaging in the UV and the transmission is excellent across the range I need. The fused silica handles my 266 nm setup without any visible solarization so far.

The fine ground edges are a nice touch—no chipping when I mounted it. My finite conjugate setup is noticeably sharper, and the S1-UV fused silica handles the narrow UV band without any issues. Exactly what I needed.
