Fused Quartz Coverslip #No2

Finally, a coverslip that doesn't ghost my UV experiments — the optical clarity at 0.20 mm is noticeably better than the borosilicate ones I used before.

The 0.20 mm thickness is exactly what I needed for my confocal setup, and the optical clarity is noticeably better than standard glass. Arrived well-packaged and undamaged.

Swapped out my old glass coverslips for these 0.20mm quartz ones and the UV transmission difference was immediately obvious on my setup. They're thin but haven't cracked once during mounting, which honestly surprised me.
