Fused Quartz Coverslip #No2

The 0.20mm thickness is spot on for my fluorescence work—no warping even under the UV lamp. Arrived in one piece, which is always my biggest worry with fragile optics.

I needed a coverslip that could handle UV excitation without autofluorescence, and this 0.20mm quartz one is working perfectly for my fluorescence microscopy. The thickness is consistent across the whole sheet, which makes focusing much easier than with cheaper alternatives.

Swapped my usual glass coverslips for these 0.20mm quartz ones and the UV transmission makes a real difference on my fluorescence imaging. They're thin but don't warp or chip when I handle them with tweezers, which was my main worry.
