SAPPHIRE PLANO-CONCAVE LENSES Download PDF document

Sapphire has excellent transmittance from the ultraviolet to the mid-infrared, it exhibits high thermal conductivity, and it has very high surface hardness, making it more resistant to scratches than BK7 or fused silica.

We supply uncoated but a range of anti-reflection coatings can be applied as well.
