ptical 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, BOROFLOAT material is produced by a float technique that yields superior surface accuracytypically 4-6 waves per inch. The resulting minimal wavefront distortion, combined with wide spectral transmission characteristics, make BOROFLOAT an excellent choice for optical windows. In addition, this material exhibits excellent thermal properties and chemical resistance. BOROFLOAT 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 Fused Silica Windows: These optical windows are precision manufactured using UV-grade synthetic fused silica. In addition to superior transmission characteristics, synthetic fused silica exhibits higher thermal properties, exceptional purity, and excellent environmental durability for demanding applications. These Windows can be supplied in Circular or Rectangular shapes sizes are from 10mm to 300mm. Surface accuracy one lambdaOptica offers all types of windows made of different materials. Special size and materials are also available upon request. In addition, We provide various Coating on optical windows.+ Read More
