Fused Quartz Coverslip #No2

Surprised how much harder the #2 fused quartz is than the regular glass coverslips I've been using on this UV setup—the 0.20mm thickness holds up through repeated cleaning without warping. Everything arrived well-packed and perfectly flat, ready to use straight out of the box.

Picked these up for fluorescence work and the 0.20mm thickness keeps them flat on the slide with no wobble. The surface is clean enough that I'm not fighting background noise in my images.

The optical clarity is outstanding for my UV fluorescence work, and the consistent 0.20mm thickness makes focusing a breeze. No scratches or bubbles at all across this batch.
