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 comparing to a singlet lens.
Achromatic cylindrical lenses are typically introduced into system designs for the highest-power laser or imaging applications, such as anamorphic projection and anamorphic photography, Dongqiao Optics can manufacture such lenses based on the custom design doublet or triplet achromatic cylindrical cemented lenses by using centering alignment device with UV curing unit, which allows us to process precision bonding and testing simultaneously. Every singlet is fully inspected before bonding.
Please check out our anamorphic lenses for more information. If you are in the stage of developing your own anamorphic lenses, don’t hesitate to contact one of our optical engineers for a free consultation to receive design input/ suggestions from the manufacturing perspective.
