Fused Quartz Coverslip #No1.5

Finally, a coverslip that doesn't warp under my microscope's heat stage. The 0.17mm thickness sits perfectly flat and the optical clarity is noticeably better than standard glass.

The 0.17mm thickness is exactly what I needed for my high-resolution microscopy—it’s surprisingly sturdy for how thin it is. No distortion in my UV imaging, which was a nice bonus.

Ordered the 0.17mm thickness ones for fluorescence imaging and they sit perfectly flat without any wobble under the objective. The UV transmission is way better than the cheaper glass slips I used before, no background haze at all.
