Achromatic lens

Achromatic lenses are normally made of BK7, fused silica and CaF2.

Special focusing systems can be designed by Photonchina’s engineer team.

LENSES MATERIALS ILLUSTRATION PROPERTIES AND APPLICATIONS
ACHROMATIC LENS Combinations of Two Optical Grade Glasses These lenses have considerably reduced values of spherical aberrations. Best used to replace single components where performance must be improved.

 

Super Small Achromatic Lens

Super small Achromatic Lenses for your specific application provide excellent wavefront quality, super small spot size and improved modulation transfer function (MTF).
