Doublet lenses corrected for chromatic and spherical aberration. Download complete lens catalogue (2MB) Also known simply as achromat, the achromatic lens consists of two or more elements, usually of crown and flint glass, such that the composite element has been corrected for chromatic aberration with respect to two selected wavelengths. In these lenses, chromatic, spherical and coma aberrations are considerably reduced. These components are designed with respect to three wavelengths: 480 nm, 546.1nm and 643.8nm. Use achromats to replace singlets where performance must be improved. Note, however, that cemented achromats cannot withstand higher laser power levels. In such cases, one may consider using air-spaced achromats. Contact us to discuss your application. |  |
