Cylindrical lens is generally used to focus the incident light on the line or change the aspect ratio of the image. It is usually linear imaging, which can control the direction of the beam.
The cylindrical lens has a cylindrical surface, which can focus the incident light on a certain dimension and stretch the image. The focal length of the cylindrical lens can be negative or positive, which is suitable for laser line generation or deformation beam shaping to cyclize the laser output.
Compared with the general spherical lens, the production of cylindrical lens will be very difficult. We should reasonably select materials, pay attention to the texture, bubbles, impurities, uniformity and other characteristics of materials, and pay attention to the control of product specifications and quality, such as scratches, dents, gloss and high-quality grinding technology.
