Application
Our synthetic material is best suited for 172nm extreme UV applications such as excimer lamps and deep UV applications (Photo-CVD and surface activation for semiconductor wafers and flat panel displays).
Product Feature
PQ170M has higher transmission level in deep UV wavelength (more than 80% at 172nm).Production size and purchase quantity is flexible, furnace cutting, trim cutting and ends glazing are available based on customers’ need. The ultimate level of chemical purity (less than 0.4 PPM of total impurities) and the extremely low bubble level ensure the lamp's long life
Product Type
PQ170M, Syntheic Quartz Tube.
