Overview: The Biconcave (Double-concave) Cylindrical Lens is generally used
to utilized to enlarge light in single dimension or change the
aspect ratio of the image. The double concave cylindrical lens can
separate input collimated light away from a line. They are best for
one-dimensional compression of images, laser line generation and
anamorphic beam shaping. General Specifications Of Biconcave (Double-concave) Cylindrical

Coating Options of Biconcave (Double-concave) Cylindrical Lens: Normally our standard Biconcave (Double concave) cylindrical
lenses are uncoated. We offer the following four typical
antireflective coatings to reduce the reflection light from both
surfaces. Choose one of them accordingly apply to your application
or discuss with us for your special wavelgnth range. | Single Layer MgF2 Coating | Multi-layer Anti-Reflective Coating | | | Boradband Anti-Reflective Coating | Dual Wavelength Anti-Reflective Coating | | |
Custom Your Own Lens: To Maximize and improve the possibility of transforming the design
to production and save time, welcome to consult and discuss with us
such as material availability, processing difficulty and
cost-efficiency. Zemax Deisgn | Zemax Deisgn | Solidworks Design | Thin Film Coating Design |
