N-BK7 Double Convex Cylindrical Lens Dia.25mm EFL50mm Wavelength 650-1050nm AR Coating

Double convex cylindrical lenses are used in optics system, laser system, scanner system and many other applications. Sunday is manufacturing circle plano convex cylindrical lens and square or rectangular plano convex cylindrical lens.

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.

Double convex cylindrical lens consists of two convex surfaces and can transform a point light source into a line light source.Usually used in optical display systems, imaging systems, optical instruments, laser systems, etc.
