Microscope coverglass, G.E. 124 fused quartz, 0.17 – 0.24 mm thick, two styles. All our polished quartz slides and cover glasses are manufactured from G.E. 124 Fused Quartz. They are polished to a 80/50 scratch/dig. This equates to a 5 micron or better finish.

G382 circular, 25.4 mm diameter, each.

G382-SQ square, 25.4 x 25.4 mm, each.

Note: ProSciTech can supply, on indent, a range of quartz products including Flasks, Beakers, Crucibles, Wool, Frits and Tubes.

Machined quartz – Optical properties

The optical properties of fused quartz let us choose between various types, because the degree of transparency defines material purity and the method of manufacture. Certain indicators are the UV cutoff and the presence or absence of bands at 245 nm and 2.73 micrometre. The UV cutoff varies from 155 to 175 nm for a 10 mm thick test sample. The presence of transition metallic impurities will move the UV cutoff towards longer wavelengths. The curves in the figure represent the average transmissions for a 10 mm thick test sample for both commercial and optical grades. Fused quartz is very efficient for the transmission of infrared radiation. Infrared transmission extends out approximately 4 micrometers, with little absorption in the “water band” at 2.73 micrometre.
