Overview: The Biconvex (Double-convex) cylindrical lenses are mainly used to
change the design requirements of the imaging size. For example,
converting a point spot to a line spot, or changing the height of
the image without changing the width of the image. They can be
applied in linear detector lighting, barcode scanning, holographic
lighting, optical information processing, computer, laser emission.
Optical cylindrical lenses are also widely used in high-power laser
systems and synchrotron radiation beamlines. At the same time, the
requirements for biconvex cylindrical lenses are getting higher and
higher, especially in high-power laser resonator cavities and long
distances line interferometers and other high-precision testing
instruments and devices.

Coating Options of Biconvex (Double-convex) Cylindrical Lens: Normally our standard Biconvex (Double convex) cylindrical lenses
are offered without coating. Some of the applications require lens surfaces to be Antireflection
coated to minimize the reflection light from each faces. We provide
four classical coatings in below as well as support custom design
wavelengths. | 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 |
