Highly reflective mirrors (HR) are characterized by a reflectivity of radiation that converges towards 100%.
The reduction of reflections on surfaces avoids disturbing light for the observer and also achieves a higher transmission as well as an improvement of the contrast.
The term "front surface mirror" is applicable to any mirror whose first boundary surface is a mirrored surface.
Short pass filters are optical edge filters, which transmit all wavelengths of the spectral range before the edge and reflect them after the edge, i.e. short-wave radiation is separated from long-wave radiation.
Longpass filters are optical edge filters, which reflect all wavelengths of the spectral range before the edge and transmit them after the edge, i.e. short-wave radiation is separated from long-wave radiation.
Band-reject filters, also called notch filters, are used to reflect predefined spectral ranges.
Depending on the light source used, a filter is needed to correct the color coordinates of the light source.
Infrared transmission filters, or infrared transmitters, are designed to let the radiation in the infrared range pass.
Cold light mirrors are designed to let infrared radiation pass through, so that the accompanying heat radiation and heat load can escape and overheating of the technical applications is avoided.
The use of heat protection filters in technical components guarantees a reduction of heat stress through high reflection in the infrared spectral range.
UV-transmitters are applied to let ultraviolet radiation pass through while the VIS and IR radiation can be adapted according the requirement.
Dichroic Beam-Splitters can be used in case of requirement for optical components, which function should be color separation or color merging.
Color-neutral beam splitters are used in optical systems in which beam paths are to be split, combined or deflected.
The focus of indium tin oxide (ITO) coatings is to create an electrically conductive surface with high transparency in the visible spectral range.
