Achromatic cylindrical lenses are ideal for eliminating spherical and chromatic aberration at the image plane, for example using monochromatic light source, achromatic cylindrical lenses can form a 50-90% smaller spot compared to singlet.
For most severe laser or imaging applications which involve cylindrical components, such as anamorphic projection, anamorphic photography, and achromatic cylindrical lenses are introduced. Hyperion Optics can manufacture based on custom design doublet or triplet achromatic cylindrical cemented lenses by using centering alignment device with UV curing unit to process precision bonding and testing at the same time. Every singlet is fully inspected before bonding.

Achromatic Cemented Cylindrical Lens An achromatic cylindrical lens can minimize chromatic aberration, so it can be used to focus a single direction of a multi-color light beam. Unlike a spherical lens that produces a point-focusing spot, an achromatic cylindrical lens can ...
An achromatic triplet lens is a compound lens consisting of three single lenses. The triplet design is the simplest to give the required number of degrees of freedom to allow the lens designer to overcome all Seidel aberrations. Calcium Fluoride and UV Fused Silica Elements ...
