Sapphire monocrystal is noted for its high mechanical strength, chemical resistance and temperature stability and additionally offers good optical transmittance from 200 nm. Wherever extreme levels of wear resistance, hardness, inertness, temperature stability and chemical resistance are demanded, sapphire is the right solution.
As one of the most valuable materials for industrial applications, natural quartz glass has a number of unique properties. It has a nominal purity > 99.99 weight per cent SiO2. Quartz glass has high temperature stability as well as displaying outstanding transmittance values in the UV and IR ranges.
Laser protection glass is made of quartz glass as this material ensures high transmittance. This is necessary, as this glass is inserted between the laser source and the workpiece to protect the laser source. So that the laser beam is not impaired or deflected, it is necessary to use a high-purity material. In addition, the glass is given a special anti-reflective coating in different wavelength ranges. On request, Schröder Spezialglas offers laser protection glass in the 20-to-135 mm diameter range with various coatings.
