The spherical lens acts symmetrically on the incident light in both directions, while the cylindrical lens acts in only one direction on the incident light. A typical application is to shape a deformed beam with a pair of cylindrical lenses. A pair of positive cylindrical lenses can be used to collimate and round the output of the laser diode. Another possible application is to focus the diverging beam onto the detector array with a single cylindrical lens. In order to minimize the spherical aberration, when the collimated beams are concentrated into one line, the collimated light should be incident on the curved surface of the lens, and when the quasi-linear source is used, the line source should be incident on the plane of the lens.

Perhaps, while we enjoy the convenience of optoelectronic products, we neglect the important parts in optoelectronic products - cylindrical mirror
As we all know, optoelectronic products are mostly composed of optical path systems, electronic devices and mechanical systems. Optical path systems play a vital role in the collection and transmission of information.
A general optical system consists of optical components such as lenses, beamsplitters, and mirrors. Its shape is usually spherical or flat. The cylindrical mirror is an aspherical lens, which can effectively reduce the spherical aberration and chromatic aberration. It is divided into a flat convex cylindrical lens, a flat concave cylindrical lens, a double convex cylindrical lens and a double concave cylindrical lens. Has a one-dimensional amplification function. Cylindrical mirrors are primarily used to change the design requirements for imaging size. For example, converting a point spot into a line spot, or changing the height of the image without changing the desired width. With the special optical performance of cylindrical mirrors, cylindrical mirrors have become more and more widely used with the rapid development of high technology. Such as line aggregation systems. Movie playback systems. Fax machines and scanning typesetting scanning imaging systems. And medical fields of gastroscopes. Laparoscopy, automotive video systems in the automotive field have the participation of cylindrical mirrors. At the same time in linear detector lighting, barcodes Scanning, holographic lighting, optical information processing, computers, laser launches. And in the strong laser system and synchrotron beam line also have a wide range of applications. At the same time, with the continuous improvement of the cylindrical mirror processing technology, has now formed a mature and efficient processing technology, its good quality reproducibility and repeatable Sex is gradually recognized by the market. At present, the process is gradually replacing the relatively backward traditional process.
As is well known, a cylindrical mirror is composed of a flat surface and a concave (convex) surface or two concave (convex) surfaces. Can be divided into flat convex cylindrical mirror, flat concave cylindrical mirror, double convex cylindrical mirror, double concave cylindrical mirror, convex and concave cylindrical mirror. The shape is as shown below:
