We started by UV-stop quartz tubes.Its surface is clear or slight blue and its cut surface is light blue.Besides its good physical and chemical capblities as common quartz tubes have, it also can filter out wavelength between 190-320nm,which stops the radiation to the body. It serves as the material of quartz halogen lamps ,high density discharge lamps and other UV light,which prevent the harm to the skin of people and things which have to be under the UV radiation .It sets out the maximum visible[...]

This clear quartz rod has high purity, elevated temperature characteristic and low coefficient of thermal expansion. It serves as the material of the bridging rod for single end halogen lamps,fiber optic lighting ,quartz making ,wafer and push rods in semiconductor indyustry .We have many specifications for your choice.The diameter ranges from 1.2mm to 25mm. And the small diameter quartz glass rods are our priority products[...]

This clear quartz tube has the typical characteriastics of high purity, good spectral transmission, well controlled dimension, lower OH and so on. It serves as the first choice of heat resistant material for halogen lamps, mercury lamps, metal halide lamps and other quartz lamps. And further processing of trim cutting, fire polishing, bending and pinching and etc. can be done according to the requirement of customers. Available specifications: Outside diameter: 1.5-350mm Wall thickness: 0.5-15mm Length: 10-3,000mm[...]
