5.0mm aspheric plastic lens with 1.8mm BFL, made from COC. Ideal for collimating or focusing light in the 450–980nm range with glass-like optical performance.
CL1C-D50F18
Description
The CL1C-D50F18 Plastic Aspheric Lens is a precision-engineered optical lens designed for high-accuracy beam collimation and light shaping across the 450–980nm wavelength range. With a 5.0mm diameter, 2.1mm height, and 1.80mm back focal length (BFL), this lens provides excellent optical control in compact system designs.
Crafted from COC (Cyclic Olefin Copolymer), this lens delivers glass-like clarity, low birefringence, and stable transmission performance. Its aspheric surface corrects spherical aberrations, enhancing beam quality and focus precision compared to traditional spherical optics.
Ideal for applications in laser modules, biomedical sensors, and compact imaging systems, the CL1C-D50F18 balances optical quality, dimensional stability, and low weight — making it a robust alternative to glass in cost-sensitive or space-constrained applications.
