Infrasolid GmbH

Infrasolid has developed a unique packaging process for its infrared radiation sources in TO-8 housing. Special soldered filter windows in hermetically sealed TO-8 housings have a broadband optical output and can be used in harsh industrial environments.

The CaF2, BaF2 and sapphire windows make the radiation sources impenetrable for gases. While standard glued windows are often affected by permeation of vapor or gases, the hermetic housing technology remains free of contamination.

The hermetically sealed housing makes the emitters suitable for usage in harsh industrial environments, explosion-endangered applications, corrosive gas mixtures, high temperature, high partial gas pressure and high humidity.

The hermetic sealing allows the use of special inert protective (noble) gases inside the package, decreasing energy consumption and increasing efficiency. Using Infrasolid's hermetic housing technology provides long-term stable and highly efficient infrared radiation sources for gas sensors and gas monitoring, material analysis as well as infrared spectroscopy.

Infrasolid’s infrared radiation sources are pulsable thermal emitters with a near black-body emittance. The technology is based on a patented emitter set-up  with patented nanotechnology made of high-melting metal. The free-standing monolithic radiating element with the nanostructured emitter surface offers numerous advantages for many applications.

The nanostructured emission layer consists of metal nanorods made by an unique PVD process. It provides a broadband and highly efficient emission of infrared radiation. To increase the optical output power the coating can be applied on both emitter sides by using the backside emitted radiation with the aid of a gold-plated reflector.

By adapting the nanostructured surface, the emission spectrum can be influenced and adapted to specific applications. Energy consumption can be reduced by not generating radiation in the unnecessary wavelength ranges. The unique and patented manufacturing process enables the flexible production of different emitter area geometries and an easy adaptation to customer-specific applications. The infrared radiators are available in an open version and in a hermetic housing.
