Achromatic Cylindrical Lenses

Achromatic 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.

Features of Achromatic Cylindrical Lenses

Features of Achromatic Cylindrical Lenses
  • One-stop customized production: Solar Valley processes various round and square achromatic cylindrical lenses according to customer requirements.

  • Material: Use optical quartz, optical glass and other optical materials.

  • 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.

  • Description of product size indicators: Maximum outer dimension of achromatic cylindrical lens: OD≤φ300mm Maximum outer dimension of square achromatic cylindrical lens: L×W≤210×210mm Center thickness of achromatic cylindrical lens T≤100mm Achromatic cylindrical lens The lens can reach the following precision levels according to customer requirements: Ultra-high precision grade: surface error <0.1μm, surface roughness <0.01μm High precision grade: surface error <0.5μm, surface roughness <0.05μm Precision grade: surface error <1μm, surface roughness <0.1μm
