976nm Aspheric Glass Lens

optical aspheric lens

factory offer optical aspheric lens

High-precision molded or polished optical glass aspherical singlet lens with 10mm clear aperture and 16.7mm effective focal length, specifically optimized for 976nm wavelength applications such as fiber laser pump sources, diode laser collimation, and free-space NIR coupling.

The aspheric profile eliminates spherical aberration and delivers a smaller focused spot with higher coupling efficiency than spherical lenses.

Anti-reflection coated at 976nm (V-coat, R<0.25%) or optional BBAR 900–1100nm.

Ideal for compact NIR laser modules, pump combiners, and OEM photonics assemblies.
