IR sources product overview
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.
Benefits
- Increased service life through the reduction of oxidation processes
- Backfilling with different gases for variation of radiation power and time constant
- High safety for explosion-protected applications
- Ideal for battery or stand-alone low power applications
JSIR 340 - C-MOSI® - based Economy IR emitter
The MEMS chip used in our infrared emitters consists of a multi-layer heating plate membrane containing a high-temperature stable metal C-MOSI® layer. The emitter chip is based on a silicon substrate with an etched backside membrane. All thin film processes are performed with standard MEMS processes and CMOS-compatible materials. The active C-MOSI® resistive layer is protected against aging and the environment.
Benefits
- Cost-effective components: standard MEMS technologies and CMOS compatible
- Effective automatic assembly processes possible due to SMD housing
- Membrane temperatures up to 800 °C for optimum radiation performance
- High modulation depth due to low thermal mass
JSIR 350 - NAC based premium IR emitter
JSIR 350 are MEMS-based infrared emitters characterized by particularly high radiant power. By combining standard silicon material technology with NAC coatings, Micro-Hybrid offers a new generation of IR MEMS products with exceptional performance.
