N-BK7 Bi Concave Cylindrical Lens Dia.6.25mm EFL-6.25mm Wavelength 350-650nm AR Coating

Double concave cylindrical lens focus or expand light in one axis only. They can be used to focus light into a thin line in optical metrology, laser scanning, spectroscopic test, laser diode, and optical processor applications.

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.
