Fused Quartz Coverslip #No5

I needed a coverslip that wouldn’t autofluoresce under UV, and this fused quartz one is crystal clear—optically perfect and exactly 0.50mm thick.

The 0.50mm thickness is dead consistent across the pack, which matters when you're stacking them under a microscope. Edges came clean with no chips, and they fit my slide holder perfectly.

The 0.50mm thickness feels substantial without being bulky, and it fits perfectly into my 25mm sample holder. Would've liked it a bit cheaper for the size.
