| 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.
