Optical Filter Glass

Optical Glass is a fundamental material used in many optical applications, including prisms, lasers, beam splitters, and other optical devices as well as semiconductors, and can be coated with half-mirror coating, total reflection mirror coating, and anti-reflective coating according to the intended use.

• Quartz Glass

  Quartz Glass is a glass made of SiO₂ as a single component and is characterized by a small coefficient of thermal expansion, a large UV transmittance, high acid resistance and mechanical strength, and high electrical resistance, compared to ordinary glass.
  Quartz Glass is used as an insulating material for lenses, prisms, mercury lamps, and electron tubes.

• Pyrex Glass

  Pyrex Glass is a special glass with chemical durability and contains 80% silicic acid and 14% boric acid, and its thermal expansion rate is about 1/3 of that of ordinary glass. Pyrex Glass, also called borosilicate glass, does not break easily even with rapid temperature changes.
  Pyrex Glass is a low thermal expansion glass with good formability and is widely used in chemical containers, tubes, and heat-resistant cookware.

• Brosilicate Glass

  Brosilicate Glass is the oldest glass with high resistance to thermal shock or sudden changes in temperature, which means it will not crack under extreme temperature changes as does the case with ordinary glass. Its durability has made it the glass of choice for high-end restaurants, laboratories and wineries.

• Fireplace Glass

  Fireplace Glass has 700-750 degrees of heat resistance, less soot, and can be used for a long time at high temperatures, allowing far-infrared rays to pass through and creating a feeling of warmth.
