86-755-82924037Achromatic cylindrical lenses are suitable for eliminating spherical aberration and chromatic aberration on the image plane and can be used to focus a single direction of a polychromatic beam to produce a linear focus point. Suitable for high-power laser systems, measurement, and imaging application systems, such as anamorphic projection and anamorphic photography, etc. The single cylindrical lens in the cemented cylindrical lens has been processed through milling, fine grinding, grinding and polishing processes to achieve an optical surface shape accuracy of ≤0.1 micron and a surface roughness Ra of ≤0.01 micron. Multiple cylindrical lenses are glued together with double lenses or three lenses. By using a centering device with a UV photosensitive adhesive curing device, precision gluing and eccentricity testing are carried out to produce achromatic cylindrical glued lenses.

Properties of achromatic cylindrical lens: Achromatic cylindrical lens can be glued with double cylindrical lenses or three cylindrical lenses. The spot size ratio produced by it is small. The achromatic cylindrical lens is pre-installed in the shell and is engraved on the shell. There is information such as the part number, the range of added transparency film, the focal length, an arrow indicating the direction the lens should face when using a quasi-linear light source, an infinity symbol indicating that the lens has an infinite conjugate ratio, and more.
