Photonics Dictionary

coating materials: Optical coating materials refer to specialized materials applied to optical surfaces (such as lenses, mirrors, or prisms) to alter their optical properties. These coatings are designed to enhance performance by controlling factors like reflection, transmission, absorption, and polarization of light. They are typically thin layers of materials (often dielectrics or metals) deposited onto the optical substrate through processes like vacuum deposition or sputtering.

The key purposes of optical coatings include:

Anti-reflection (AR): Reducing reflection and increasing transmission of light through the optical surface.

Reflective coatings: Enhancing reflectivity for mirrors or beam splitters.

Filters: Selectively transmitting or blocking specific wavelengths of light (e.g., bandpass or longpass filters).

Protective coatings: Providing durability and resistance to environmental factors like moisture or abrasion.

Polarization control: Manipulating the polarization state of light passing through or reflecting off the surface.

The choice of materials and the design of these coatings depend on the intended application, desired optical performance, and environmental conditions in which the optics will be used.
