HISpower series

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 to the front through the housing window in order to achieve maximum efficiency. All our emitters offer minimum drift at a constant electrical resistance. Infrasolids IR 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 allows soldered sapphire, CaF₂ and BaF₂ windows for use in a wide temperature range of -25 °C up to +85 °C.

Infrasolid’s infrared radiation sources are pulsable thermal emitters with a near black-body emittance. Based on a patented nanotechnology and a patented emitter set-up made of a high-melting metal, the free-standing monolithic radiating element and the nanostructured emitter surface offer numerous advantages in many applications.
