Cerium Doped Quartz Glass Tubing Yellow Color Uv Blocking

Cerium doped fused quartz tubes and sleeves

is a high purity semi-synthetic quartz with Cerium dopant blocking UV-transmission below 382 nm. It is typically used in applications in which high surface quality, good homogeneity and low bubble content are required. These include:

Short arc lamps

High energy laser flash lamps

Continuous pulse laser lamps

Solarization resistant lamps

Laser excitation lamps

Cerium not only inhibits part of the UV spectrum but also improves laser efficiency due to its fluorescence. ZCQ proprietary multi-step production process allows the drawing of tubing without contact with any tooling. This eliminates any surface contamination and produces a nearly blemish free surface, no airlines, a very low bubble content and high homogeneity.
