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 produce a linear focusing spot. Our cylindrical achromatic doublets are pre-installed in a Ø1" housing for ease of use. The housing is engraved with the part number, the range of the increased projection film, the focal length, the arrow indicating the direction the lens should face when the quasi-linear light source, and the infinity symbol indicating that the lens has an infinite conjugate ratio. As one of the professional optical components companies, Ecoptik (also known as BRD Optical) can provide various achromatic cylindrical lenses. If you have a demand, please feel free to contact us.
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.
We are capable of producing up to 150mm in diameter with reliable anti-reflective coatings, centering strictly controlled on optical edging device, and surface accuracy is defined on Zygo. Further, we also help customer to adopt Chinese CDGM or NHG equivalents in achromatic cylindrical design, this is particularly flexible solution in LRIP cases.
Please check out our anamorphic lenses for more information. If you are in the stage of developing your own anamorphic lenses, don’t hesitate contacting one of our optical engineers for free consultation to receive assistant from manufacturing perspective. Talk to one of our skilled technicians for more details.
