JGS1 Achromatic Cylindrical Lens Dia.12.5mm EFL25mm Wavelength 650-1050nm AR Coating

An achromatic cylinder lens is a type of doublet lens consisting of a positive low-index (crown) element and a negative high-index (flint) element cemented together. The two materials are designed to work together to reduce spherical and chromatic aberrations. 

Cylindrical lenses are generally used to focus incoming light onto a line or to change the aspect ratio of an image.They are usually linear and control the direction of the light beam.A cylindrical lens has a cylindrical surface that enables incident light to focus on a dimension and stretch the image. The focal length of the cylindrical mirror can be negative or positive and is suitable for laser line generation or deformation beam shaping to cyclize the laser output.Cylindrical lens compared with general spherical lens, cylindrical lens production will be difficult, to reasonable selection of materials, pay attention to the texture of the material, bubbles, impurities, uniformity and other characteristics, pay attention to the product specifications and quality control, such as scratches, dents, luster, high quality grinding technology.

An achromatic cylinder lens is a type of doublet lens consisting of a positive low-index (crown) element and a negative high-index (flint) cemented together. The two materials are designed to work together to reduce spherical and chromatic aberrations. The Typical applications include line generation with laser diodes, focusing a diverging beam onto a linear detector array or using a pair of cylindrical lenses to collimate and circularize  the output of a laser diode.
