Detailed Product Description

glass tube:

A new type of quartz glass material, with high temperature resistance and excellent shock resistance properties, used in infrared radiation light source application.

The main ingredient is SiO2. 
Transmittance >= 80% @ 0.8-3um in wave length

The black quartz tube could keep ultraviolet radiation and major portion of the visible light and trun it into infrared radiation.

Compare with clear quartz heating tube and milky quartz heating tube, black quartz tube has so many obviously advantages: Having good infrared radiation efficacy of milky quartz tubes and high temperature resistance, recrystallize resistance properties of clear quart tubes.

Especially suitable to light-wave tube, high-power infrared radiation lamp, compact infrared radiation light source and other infrared radiation light source which visible light is not allowed
