(OH<4.00 ppm)

Used mainly in high performance and high temperature lamps such as quarz halogen, mercury, ultra-violet (UV) lamps, semiconductor quartz ware, wave-guide handles, thermocouples and high temperature products.

(OH<1.00 ppm)

Within the high specification of this material the extremely low hydroxyl level makes it the preferred material for producing metal halide lamp envelopes and other applications requiring extremely low hydroxyl content.

Doped with titanium

This material is commonly called 'germicidal' or 'ozone free' quartz glass. It is produced to transmit UV-A and UV-B while blocking the deep high wavelengths. This makes it the ideal material for many disinfecting applications and various other UV treatment applications.
