| Synthetic Fused Silica 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.
Our synthetic quartz material (ES equivalent) has high transmittance in
the ultraviolet wavelength, and has excellent thermal expansion and thermal
shock resistance.
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.
