Product Detail:

Quartz glass is the special glass of the single silicon dioxide.

The material has low thermal expansion,good refractoriness,excellent chemical inertness,fine electric isolation, low and stable supersonic delay-action.the best transparent form transmits UV,and IR as well as visible light and higher mechnical properties than these of usual glass.

Quartz glass is made by melting either naturally occurring crystalline quartz or silica produced synthetically from silicon tetrachloride at the high temperature of 1800°c,The resulting fusion can be formed into rod ,tubing,etc As the usual glass ,quartz glass realize the thernal process to tubes and rods at high temperature.also can be machined with diamond or cilicon abrasive tools at a high speed and cool condition,making different apparatus and special products.

This cold mirror is specially designed to reflect more than 95% average of ultra-violet rays from 350-450 nm and transmit more than 90% average 550 -1200nm at 45 degrees angle of incidence.

We can design according to your requiry. Supply with high quality and inexpensive quartz glass for you.

Application:

Plastic daubing, wooden floor, furniture, decoration, paper-printing, glazing etc.

It is used to solidify photosensitive inks in semiconductor industry, printed circuit board industry and electronic components industry.

It is also popular in optic industry and photoelectric industry as well as UV conglutination industry.

Cold filters are designed to protect the more sensitive substrate from direct infra-red radiation. They also protect the UV lamps and reflector assembly from dust and other contaminants, particularly when the lamphead is inverted. The cold filter is manufactured from material that is naturally transparent to UV, but reflective to infrared radiation.
