Description
Factory Custom Achromatic Triplet Lenses with Edge Blackening
We manufacture custom achromatic triplet lenses tailored to your optical and mechanical requirements.
Combining multiple crown and flint elements in cemented or air-spaced designs, our triplets deliver superior chromatic and spherical aberration correction compared to standard doublets.
Each lens undergoes precision edge blackening to suppress stray light and enhance image contrast in demanding imaging and laser applications.
Available in diameters from 10 mm to 150 mm, EFLs from 15 mm to 1000 mm+, with BBAR or custom coatings and optional mechanical mounting.
Trusted by OEMs in industrial vision, defense, and scientific instrumentation.
