Технические характеристики
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.
Plano Convex cylindrical focus the beam in one direction but not in the other.It is generally used for shaping deformed beams, such as for collimating and circularizing the output of laser diodes, and for focusing diverging beams into a line.
Plano Convex lens available in a variety of materials, including BK7, fused quartz, etc., and can be customized to the required size, and can be coated with anti-reflective films of different wavelengths according to the situation of use.
