IR Sources

Our IR emitters ensure reliable and precise measurement results in NDIR gas analysis. For every application, we have the optimal combination of engineering and packaging technologies and MEMS emitter chips, produced in our own factories.

Micro-Hybrid JSIR emitters are NAC or C-MOSI® MEMS-based infrared emitters with true blackbody radiation characteristics. From economy IR emitters for mass applications to high-end radiation sources for demanding measurement tasks, our JSIR emitters cover all application areas for measuring and monitoring gas concentrations.

Micro Hybrid IR emitter in comparison

JSIR infrared sources are optimized for the mid-infrared wavelength range (MIR) between 2 and 15 µm. Our portfolio includes three emitter chip types (size of active area 2.2 x 2.2, 1.0 x 1.0 or 0.65 x 0.65 mm²) in different assembly versions. The airtight soldered HermeSEAL® variants are exclusively available at Micro-Hybrid.

  • JSIR 340 CMOS compatible chip ideal for high volume applications,
  • JSIR 350 NAC MEMS chip with high modulation frequency
  • JSIR 360 Black Silicon IR Emitter Chip for long-wavelength gases

The selection of the right IR source for each NDIR gas detection application depends on various parameters such as package, chip type, active area, backfilling, filter, and many more.

HermeSEAL® Technology

This unique packaging process was developed by Micro-Hybrid in cooperation with Jenoptik: By soldering a metalized filter to the reflector or cap, hermetically sealed IR emitter with high efficiency are created. HermeSEAL emitters can therefore also be used in harsh environments for which conventional IR components are not suitable. These include high temperatures or high humidity.
