Achromatic lenses are normally made of BK7, fused silica and CaF2.
Special focusing systems can be designed by Photonchina’s engineer team.
Normal Achromatic Lens
|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).
