Sapphire Convex Lens

Sapphire plano-convex lenses are suitable for high power, high-pressure applications, and vacuum or corrosive atmospheres. Sapphire material is extremely hard and resistant to corrosion, high compressive strength and a high melting point, and excellent thermal conductivity. Transmission range is from 150 to 5,000 nm
