Achromat Lens
Achromatic doublet lenses have significantly better optical performance than singlet lenses in visible imaging and laser beam manipulation applications. Achromat Lenses are consist of two elements, usually of a positive low-index crown glass cemented to a negative high-index flint glass that have been corrected for chromatic aberration with respect to two or more selected wavelengths. We provide achromatic lenses consisting of two elements. These lenses have considerably reduced not only chromatic aberration bust also spherical aberration and coma aberration. These are designed with respect to three wavelength 480.0nm, 546.1nm and 643.8nm.

Achromatic lenses are normally made of BK7, fused silica and CaF2. Special focusing systems can be designed by Photonchinaâ??s engineer team. Sizes from smallest diameter of 3mm to biggest of over 100mm are all available. Normal Achromatic Lens 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). Feature Small diameter size up to 3mm Short focal length, such as 5mm Strict quality control, excellent quality AR-coating, mounts services
Achromatic lens is designed to limit the effects of chromatic and spherical abberation. It is corrected to bring two wavelengths(typically red and blue) into focus in the same plane. Achromatic lenses can be doublets or triplets, with two or three individual glasses cemented together.
