| 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.

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
