Plano Concave Lens

 
Plano-concave lenses have a negative focal length and are used for image reduction and divergence applications.

When combined with a convex lens, it is possible to arrange the optical system, such as extending the working distance or expanding the LD beam. The general usage is that the plano-concave lens is the same as the plano-convex lens, and the parallel luminous flux is directed toward the concave side.

The products shown are uncoated, but we also accept custom orders for anti-reflection coating and other coating. Please contact us for the coating simulation data and the pricing.
