OptoSigma supplies a wide selection of optical thin film coatings. These coatings are often provided as part of the optical component but they may also be ordered separately to be applied to an uncoated element. For example, it is possible to apply an Anti-Reflection coating to any uncoated lenses, windows or optical fibers. Also reflecting coatings may be applied to uncoated substrates to form mirrors or partial reflectors. To make this process simple we have listed some of our most common standard coatings. To order you simply append the coating suffix to the base part number and specify the surfaces to be coated. If you don't find the exact coating you need please ask us to provide you with a custom solution. Our coating engineers will use the latest design software and production techniques to provide you with the coating you require.

High Performance Anti-Reflection Coatings increase substrate transmission and reduce surface reflection over a specific wavelength range. If system requirements are such that transmission improvement is required for only a relatively narrow wavelength interval, single layer coating may be sufficient. However, if uniformly higher transmission is desired over a wide wavelength interval, or if suppression of reflected energy is critical, multilayer antireflection coatings such as our High Performance Anti-Reflection Coatings must be used.
