Doublet lenses are transparent optical components consisting of two pieces of optical glass with surfaces so curved (usually spherical) that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object.
We offer a wide range of custom and standard lenses for almost any application.

A special form of doublet lens is the achromatic lens. These consist of two 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, 546nm and 644nm. Use achromats to replace singlets where performance must be improved.

Range of dimensions: 2mm – 200mm

Highest available surface figure: λ/10 (DIN: 3/0,2)

Highest available surface quality: 20-10 S/D (DIN: 5/2x0,1)

In addition to our custom components, we offer a selection of standard lenses for prototyping and experimenting. Please see the “Download” tab for a list of available products.
