K9 Plano-Convex Lens, 650-1100 nm AR Coating

SO-L01 B-band plano-convex lenses are coated for reduced reflection from 650 to 1100 nm, covering common red and near-infrared diode-laser wavelengths. The K9 substrate provides consistent optical quality for beam focusing, fiber-coupling benches, NIR illumination and compact imaging assemblies that do not require deep-IR materials.

Product Overview

Configure K9 Plano-Convex Lens, 650-1100 nm AR Coating around focal geometry and coating

Choose focal length according to the required convergence angle and working distance, then verify the back focal length against the mechanical layout. The B coating is specified as average reflectance below 0.5% across the stated wavelength range.

This version is best matched to red and near-infrared sources from 650 to 1100 nm, including many 780, 808, 850, 940 and 1064 nm systems.
