2.9mm COC aspheric lens with 2.5mm back focal length. Optimized for 450–980nm, offering glass-like optical performance in compact applications.
CL1C-D29F25
Description
The CL1C-D29F25 Plastic Aspheric Lens is a high-performance micro-optical element engineered for collimating or focusing light across the 450–980nm wavelength range. With a 2.9mm outer diameter, 1.55mm height, and a 2.5mm back focal length (BFL), this lens is ideal for compact and portable optical assemblies.
Manufactured from COC (Cyclic Olefin Copolymer), a premium optical polymer known for its exceptional transparency, low birefringence, and low moisture absorption, the CL1C-D29F25 offers performance approaching that of glass lenses in a lightweight, moldable format. The aspheric surface minimizes spherical aberrations, improving beam quality and enabling precise optical alignment.
This lens is particularly well-suited for integration into optical sensors, laser modules, medical diagnostics, and consumer electronics where size, weight, and clarity are critical.
