Metallic Reflective Coating CK9M001
Metal reflective films are usually composed of a single metal layer, which can be plated with metals such as gold, silver, and aluminum, and have the advantages of high reflectivity and wide spectral range. Generally, metals have a high extinction coefficient. When a beam of light is incident from air onto a metal surface, the amplitude of the light entering the metal rapidly decays, resulting in a corresponding decrease in the energy entering the metal and an increase in the reflected energy. The larger the extinction coefficient, the faster the attenuation of light amplitude, the less light energy enters the metal interior, and the higher the reflectivity. Protecting aluminum: The commonly used metal thin material in the ultraviolet region is aluminum, while aluminum (and silver) are commonly used in the visible light region. Protecting Silver: Gold and silver are commonly used in the infrared region. Protective gold: It has reflectivity in the infrared light region after 0.65 microns.

Polarizing Beamsplitter Coatings
Optical Coatings
Rsgx
Polarizing beamsplitter coatings exploit thin film polarization effects at oblique incidence. Prism and plate types are available. Prism coatings offer broader wavelength ranges and high polarization, but are harder to manufacture in large sizes and have lower laser resistance. Plate polarizers have narrower bands but can be larger and withstand stronger lasers, so they are often used in high intensity laser systems.

Antireflection Coatings
Optical Coatings
Rsgx
Reflection at optical component surfaces causes optical energy loss. Transparent dielectric antireflection films reduce this loss. Lower reflected intensity increases transmitted intensity and improves image clarity. Common materials include magnesium fluoride, titanium oxide, lead sulfide, lead selenide, ceramic infrared antireflection coatings and vinyl silsesquioxane hybrid films. In general…

Partial Reflection Coatings
Optical Coatings
Rsgx
Reflective coatings increase optical surface reflectivity; partial reflectors divide light into reflected and transmitted portions. They are used in beamsplitters, output couplers and interferometers. Beamsplitter coatings include single wavelength partial reflectors and broadband partial reflectors.

High Reflection Coatings
Optical Coatings
Rsgx
Dielectric high reflection coatings exploit reflection and transmission at each interface of a multilayer stack. Appropriate layer thicknesses make reflected waves interfere constructively for high reflectivity. Metals generally have high extinction coefficients: light entering from air attenuates rapidly inside the metal, reducing internal transmission and increasing reflection. Higher extinction coefficients produce faster amplitude attenuation…
