UHP Quartz Tube

I. Application

Ultra high pressure projection lamp, high purity capillary lamp and cinema lamp

II. Product Features

Extremely high purity (the total impurity content is about 10ppm), very low content of alkali metals (the content of alkali metals is less than 0.5 PPM) and the ultimately low OH level (can reach less than 0.5 PPM), very strong anti-crystallization performance. After making lamp, it has merit of small volume, high brightness and long life performance.
