Thermal infrared emitter with CaF₂ window, hermetically sealed
HIS2000R-C300-9 is a NiCr filament based thermal infrared emitter in a hermetically sealed TO-8 package with a glued CaF₂ window. This guarantees better long-term stability. The standard cap allows a simple replacement in existing applications.
High-power infrared sources in TO-8 housing
HISpower series emitters have an integrated gold-plated reflector that directs the radiation emitted from the rear filament side to the front through the housing window in order to achieve maximum efficiency and optical output power. All our emitters offer minimum drift at a constant electrical resistance. Infrasolid’s infrared emitters are characterized by a very low temperature coefficient of electrical resistance. Therefore, the hot resistance and the cold resistance are almost identical which eases the electrical control of the IR sources. Infrasolid’s advanced packaging technology SOLIDSEAL® allows soldered sapphire, CaF₂ and BaF₂ windows for use in a wide temperature range of -25 °C up to +85 °C.

INFRASOLID® nanostructure technology
Infrasolid’s patented nanostructure technology allows the fabrication of extremely thin and very heat-resistant black optical coatings. They are already used in our thermal infrared light sources but also in optical detector technologies and for stray light absorption in optical measurement systems. The broad spectral range of high absorption extends from UV up to far infrared wavelengths. A structuring of the black coatings can be done by photolithography to realize very small structures or local areas of blackening. The deposition is done on flat substrates. Temperature-sensitive materials, such as plastics, can be coated using our low temperature black coating process.
