Achromatic Cylindrical Lens
Achromatic Cylindrical Lens An achromatic cylinder lens is a type of doublet lens consisting of a positive low-index (crown) element and a negative high-index (flint) element 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.
