Description

Potassium Chloride Crystal Substrates Description

Sodium chloride, potassium chloride, potassium bromide single-crystal uniform texture and transparent, has a high infrared transmittance, the transmittance greater than 90% when thickness less 10mm and in the range of 4000-500cm-1, no impurity absorption. Potassium chloride crystal substrates can be used a laser window material, and the optical performance is excellent.
