The cylindrical gold-coated mirror is an optical reflector with a cylindrical reflective surface. Parallel incident light can be focused to a line by reflection from the cylindrical surface, and has a positive focal length. The focal length of a plano-concave cylindrical reflector is half the radius of curvature of the cylindrical surface. It is suitable for light focusing applications. GIAI provides cylindrical reflectors with no coating or coating. The reflective coating options include ordinary protective aluminum film, protective UV reflective aluminum film, protective silver film, and protective gold film.

Advantages of cylindrical gold-plated reflectors
High reflectivity: Gold is a precious metal with extremely high reflectivity, especially in the infrared band. This makes gold-plated reflectors widely used in infrared optical systems.
Corrosion resistance: Gold has stable chemical properties and is not easy to oxidize, so gold-plated reflectors have good corrosion resistance and can maintain reflective performance for a long time.
High hardness: The gold film has high hardness, is not easy to scratch, and can protect the reflective surface.
Good thermal conductivity: Gold has good thermal conductivity, which helps to dissipate heat and increase the service life of the reflector.

Application of cylindrical gold-plated reflectors
Laser system: used to focus or collimate laser beams and change the shape of beams.
Optical instruments: used in optical instruments such as telescopes and microscopes to improve imaging quality.
Infrared imaging system: Since gold has high reflectivity in the infrared band, gold-plated reflectors are widely used in infrared imaging systems.
Solar thermal collector system: used to concentrate sunlight and improve the efficiency of solar energy utilization.
