Crystals such as sodium chloride (NaCl), potassium bromide (KBr) and potassium chloride (KCl) are uniform, bright and high transmittance within 0.250-20 μm when thickness less than 10mm, and no impurity absorption. These single crystals are ideal materials for making optical elements for prisms, lenses, filters, and various windows in infrared devices and optical instruments.
OST Photonics offers high quality KCl substrates for researchers and industries. Crystal orientation, size and thickness can be customized according to your requirements.
