Optical Windows
Windows are optical glass with polished faces that are relatively parallel. They are used to protect laser output. Always windows are AR coated to eliminate reflection, so AR coated windows offer improved transmission when used in industrial displays or computer monitors. Their high transmission makes them ideal for most industrial and laser protecting applications. Optical Windows ( Borofloat)
- Low Coefficient of Expansion
- Visible to Near Infrared Transmission
- High Resistance to Thermal Shock
- Borosilicate is Chemically Resistant
Borosilicate optical windows are ideal for high temperature, harsh environment applications. Unlike common borosilicate that is drawn flat, BOROFLOATTM material is produced by a float technique that yields superior surface accuracy-typically 4-6 waves per inch. The resulting minimal wavefront distortion, combined with wide spectral transmission characteristics, make BOROFLOATTM an excellent choice for optical windows. In addition, this material exhibits excellent thermal properties and chemical resistance. BOROFLOATTM is about three times more resistant to thermal shock than standard soda lime glass. It has the thermal expansion properties of Tempax® or Pyrex® without the straw yellow color. Chemical resistance includes water, saline solutions, neutral and acidic solutions, chlorine, bromine, iodine, and organic substances. Sizes From 10mm to 250mm in thickness of 1mm to 8mm
