Fused Quartz Coverslip #No1.5

The 0.17mm thickness is perfect for my high-magnification microscopy work—much clearer than standard coverslips. It’s noticeably flatter too, which reduces drift during long imaging sessions.

Switched from glass to these 0.17mm quartz slips for UV work and the transmission difference is actually measurable on my setup. They're thin enough that focus stays consistent across the slide, which was my main annoyance before.

The 0.17mm thickness on these is spot-on for my high-magnification work, and the optical clarity is noticeably better than the borosilicate slips I used before. Edges are clean with no chipping so far.
