        Optical Cylinder Lens

        Cylinder Lenses are offered in both plano-concave and plano-convex configurations, they are typically used to focus incoming light to a line, or to change the aspect ratio of an image. Cylinder Lenses are available with positive or negative focal lengths, they are used for the optics, lasers, medical science, electronics, tele-communication and others.

        Worldhawk can offer cylinder Lenses include convex cylindrical lens, concave cylindrical lens, meniscus cylindrical lens, and doublet achromatic cylindrical lens ect. Choose from N-BK7 glass, UV fused silica, or CaF2, all of which are available uncoated or with an antireflection coating.

        Worldhawk can provide various kinds of cylindrical lens with high precision, We are proud to be one of the few suppliers can detection the radius and flatness about the cylindrical lens in China. Absolutly can ensure all the products are qualified.

        +1  Cemented Achromatic Doublets
        Achromatic lenses consist of two optical components cemented together to form an achromatic doubled, which is computer optimized to correct for on-axis spherical and chromatic aberrations. 
          +2  Cemented Achromatic Triplets 
        An achromatic triplet is the simplest lens that corrects all primary chromatic aberrations. These triplets consist of a low-index center element cemented between two identical high-index outer elements and feature good on-axis and off-axis performance.

        +3  Achromatic Doublet Pairs 
        Worldhawk offers Matched Achromatic Pairs for use in the visible or NIR spectral range. Matched Achromatic Pairs are ideal for image relay, NA conversion, or image magnification.
          +4  Air-Spaced Achromatic Doublets 
        Worldhawk' selection of air-spaced achromatic doublets offer diffraction-limited spot size, superior aberration correction, and higher damage thresholds than traditional cemented doublets. They have been designed for use across broad wavelength ranges with minimal aberrations.

        +5  Negative Achromatic Lenses
        Consisting of two optical elements cemented together, negative achromats are corrected for color and on-axis aberrations. Used predominantly as Barlow lenses to extend focal lengths, they are often combined with positive achromatic mirror systems and imaging lenses.
