600-1100nm Aspheric Glass Lens

d6 f8 optical aspheric lens

factory offer optical aspheric lens

High-precision optical glass aspherical singlet lens molded or polished from OHARA D-ZK2N low-dispersion crown glass (nd≈1.589, νd≈61), with 6mm clear aperture and optimized aspheric profile to eliminate spherical aberration and improve spot quality.

Broadband anti-reflection coating 600–1100nm (Ravg<0.5%) makes it suitable for visible-to-NIR applications including 635/780/850/940nm laser diode collimation, miniature imaging lenses, and sensor illumination modules.

Available in multiple effective focal lengths (EFL 3–50mm customizable). Edge blackening and custom NA/coating wavelengths supported for OEM integration.
