Sapphire Concave Lens

With one concave surface and one plane surface, Sapphire Concave Lenses have negative focal lengths.

Sapphire concave lenses are ideal for light projection and expanding the focal length of an optical system.

We have developed a super polishing process that enables us to fabricate Sapphire concave lenses with tighter manufacturing tolerances.
