Cylindrical Lenses

Achromatic Cemented Cylindrical Lenses

cylindrical achromatic doublets are used to focus polychromatic light in one direction only while minimizing chromatic aberration. This creates a line focus rather than a point focus, as seen in spherical lenses. Cylindrical lenses are desirable for various experimental setups, including beam shaping, laser projection, and holography. Cylindrical doublets drastically reduce chromatic aberration, and can produce a diffraction limited focus in one direction when used with monochromatic light.

Description

An achromatic cylinder lens is a type of doublet lens consisting of a positive low-index (crown) element and a negative high-index (flint) cemented together. The two materials are designed to work together to reduce spherical and chromatic aberrations. The Typical applications include line generation with laser diodes, focusing a diverging beam onto a linear detector array or using a pair of cylindrical lenses to collimate and circularize the output of a laser diode.
