Quartz Glass Tube
What is quartz glass tube?
JGS-2 (UV optical quartz glass). ... It is an optical quartz glass made by oxyhydrogen flame melting and is suggested for applications in the wavelength range of 220-2500 nm !
Applications of quartz tubes

How are quartz tubes made?
This is the most common method used to produce quartz glass in a continuous process. The quartz sand is melted in a tungsten crucible that contains electrical heating elements; the fused material flows down from the crucible through a bottom mould where it is shaped into tubes, plates and rods.
Properties of Quartz Glass:
- Extreme wide spectral transmission range from deep UV to middle IR.
- High optical transmission and low optical absorption.
- Low variation and disturbance of the refractive index in one solid piece and optical homogeneity from one melt to the next.
- High resistance to high intensity laser radiation, which also applies to the UV spectral range (e.g. excimer laser).
- High application temperature 1200 degrees C --- almost four times higher than ordinary glass.
- Low thermal expansion coefficient resulting in an extremely high temperature shock resistance allowing rapid heating & cooling.
