K9 Plano-Convex Lens, 1050-1700 nm AR Coating

SO-L01 C-band plano-convex lenses use an antireflection coating designed for 1050-1700 nm. This range supports 1064 nm laser setups as well as short-wave infrared and telecom-adjacent optical assemblies where a K9 lens is suitable and lower near-infrared surface loss is required.

Product Overview

Configure K9 Plano-Convex Lens, 1050-1700 nm AR Coating around focal geometry and coating

The positive focal length makes the lens suitable for focusing a collimated beam or collimating light from a compact source. Confirm substrate transmission at the exact operating wavelength, and use the listed back focal length and center thickness when defining detector, fiber or housing positions.

Select the C-band coating for systems concentrated above 1050 nm. For broadband visible-to-NIR instruments, the AB-coated version provides the more appropriate wavelength coverage.
