Description
Sapphire window is made from synthetic sapphire and can be
made much thinner than BK7 windows. It is highly durable with a wide
transmission range due to its highly abrasion-resistant, with hardness
approaching that of diamonds. Sapphire window is best suited for scratch
resistance application that requires better transmission over a wide range
spectrum.
