Product Description


Feature of quartz disc quartz glass plate:

1.The optical quality of quartz glass has the originality, it both may penetrate the extreme ultraviolet.

2.Is the best of all ultraviolet materials, and may penetrate the ultraviolet and the near-infrared spectrum.

3.The thermal-expansion coefficient minimum.

4.The chemical stability is good, the air bubble, the stripe, the uniformity, the double refraction have may compare favorably with the general optical glass.

5.Therefore it is works originally in each kind of bad field,has the high stability optics coefficient and the essential optical material.

6.Mainly applies in the high temperature window of war industry, laser, metallurgy , optical instrument, stage light.
