factory custom achromatic lens

High-precision cemented achromatic doublet (and triplet option) lens assembly, composed of positive crown and negative flint optical glass, designed to correct axial chromatic aberration and spherical aberration over the visible spectrum (typically 400–700nm or customized bands).

All lenses are fine-annealed, centration-matched, cemented with low-stress optical adhesive, and feature edge blackening (black ink or painted periphery) to suppress stray light and ghost reflections.

Ideal for high-resolution imaging, collimators, microscope objectives, laser focusing systems, and machine vision lenses. Available in multiple focal lengths, diameters, AR coatings, and custom centration grades for OEM optical designs.
