Details

         
Positive Achromatic Cylinder Lenses are made by bonding two types of cylindrical lenses with different refractive indices and dispersion rates. They can greatly reduce chromatic aberration and spherical aberration, and better focus incident light into a line. The double bonding design also further optimizes the performance of the lens.
Therefore, compared to a single lens with equal diameter and focal length, achromatic lenses have significant advantages. More suitable for broadband light sources, it can significantly reduce color difference and produce concentrated lines with less dispersion or clear irregular shaped images. It is widely used in related fields such as laser shaping and laser projection.
Guangtan Intelligent provides various sizes and focal lengths of achromatic positive adhesive cylindrical lenses to meet your application. At the same time, double-sided anti reflective films are coated over a wide spectral range (VIS, NIR) to reduce surface reflection and enhance transmittance. Guangtan Intelligent can also provide customized services according to your needs.
