HISpower series

High-power infrared sources in TO-8 housing

HISpower series emitters are powerful and high-efficient infrared sources that are used in high-precision and stationary gas detection and gas monitoring (e.g. CO, CO2, NO, SO2, VOC, hydrocarbons), in infrared spectroscopy and as calibration source.

These pulsable thermal infrared sources feature a very high radiant power in the entire infrared spectral range due to the large emitter area and the high and broadband emissivity. The radiation element is coated on both sides with the nanostructured emission layer. An integrated reflector directs the backside emitted radiation to the front through the housing window. Thus, a maximum optical output power and a maximum efficiency can be achieved. Infrasolid’s hermetic housing technology enables soldered sapphire, CaF2 and BaF2 windows for use in harsh environments and a wide temperature range of -25 °C up to +85 °C.

The hermetic sealing allows the use of special inert protective (noble) gases inside the package. Thus, energy consumption can be decreased and efficiency is increased.


Pulsable thermal black-body infrared source mounted in an industry standard TO-8 package.

Patented nanostructured radiating element achieves up to 500% more detection signal!

Lower radiating element temperature of 630 °C increases lifetime!

Soldered, high-quality filter windows guarantee long-term stable operation. Leakage tested!

Wide wavelength range enables a broad range of applications.
