describe
Aluminum cylindrical reflector is a specially designed optical element used to focus or diffuse light in one dimension while maintaining the propagation of light in a direction perpendicular to that dimension. This type of reflector utilizes the shape of a cylindrical surface, where its reflective surface is curved, similar to a portion of the surface of a cylinder. The surface of aluminum cylindrical mirrors is usually coated with an aluminum film to increase reflectivity, especially in the visible and ultraviolet light bands. This type of reflector is very useful in optical experiments, laser systems, spectroscopy, imaging techniques, and other applications that require precise control of the direction of light propagation.

Working principle
The working principle of aluminum cylindrical mirrors is based on the geometric characteristics of their cylindrical shape. When light shines on a cylindrical reflector, due to the curvature of the cylinder, the light will be focused or diffused in the direction perpendicular to the cylinder axis, while the light will not undergo significant changes in the direction parallel to the axis. This enables aluminum cylindrical mirrors to achieve one-dimensional optical operations, such as one-dimensional focusing or diffusion, without affecting the propagation of light beams in another dimension.
manufacturing process
- Shape processing: Firstly, it is necessary to form the precise shape of the cylindrical surface through precision machining techniques such as computer numerical control (CNC) grinding and polishing.
- Aluminum plating: Then, a thin aluminum film is uniformly deposited on the processed cylindrical surface through methods such as physical vapor deposition (PVD) to improve reflectivity.
- Protective film: There may also be a layer of protective film covering the aluminum film to protect it from damage and further improve reflection efficiency and durability.
