The fused quartz material used for our Quartz Discs, Quartz Microscope Slides, and Quartz
Cover Slips is a high quality, high purity GE124 quartz.
This quartz material is well documented and used in many microscopy applications.
Fused quartz is an amorphous, glassy material.

Optical Transmission
The curve shows the typical optical transmission curve with the absorption edges
for GE 124 from the UV through visible into the infra-red range. In the typical
250-290nm range for UV microscopy applications the material exhibits excellent transmittance.
