Anti-reflective coatings (AR) are an important part of optical systems consisting of a large number of lenses or other optical components where the highest possible transmitted energy is required. The main task of anti-reflection coatings is to increase the spectral range and reduce the residual reflection.
Filtering coatings (interference filters) are designed to separate the required spectral range from the continuous radiation spectrum. Beam splitting coatings are designed to separate the incident beam into reflected and transmitted ones with a given intensity ratio.
Transmission of a quartz window with a conductive coating applied (the second surface of the window is not covered). The resistivity of the film is 0.0016 Ohm * cm.
Coating application on optical elements
Coatings - thin films of various substances: metals, metal oxides, dielectrics, etc., - are applied on the refractive and reflecting surfaces of components, which allows you to change, if necessary, the characteristics of radiation that interacts with optical components.
Different optical coatings are used depending on the purpose of the optical components.
The Opto-TL company specializes in applying the following types of coatings:
Coating can be applied in a wide spectral range: from the ultraviolet region, starting at 355 nm, to the infrared region (18 μm).
For deposition, the electron beam method and the method of resistive evaporation are used. Vacuum facilities at "Opto-TL" are equipped with the necessary control instruments: spectral (multispectral) and quartz sensors.
The final control of coatings is carried out on digital spectral instruments covering the following ranges: 200 nm - 1 micron, 1 micron - 2 micron, 1.5 micron - 25 micron.
