Premium infrared emitter with a high performance nanoamorphous carbon membrane. This achieves membrane temperatures of up to 850 °C for high and long-term stable radiation output. The JSIR 350 IR emitter in the HermeSEAL® option is a high performance emitter for particularly demanding gas analysis applications in medicine, industry and aerospace.

The packaging version in the standard TO39 housing with reflector and window (SiARC) is suitable for measurement distances from 2 cm.
and optimizes the emission in the wavelength range from UV to 15 µm. Due to the HermeSEAL® technology option, this IR illuminator can be used in harsh environments and is insensitive to high temperatures, humidity or aggressive media.

In the patented HermseSEAL® packaging process, filters are connected to the housing by soldering instead of the conventional adhesive technology. This is the only way to ensure that the inside of the housing is hermetically sealed and the sensitive membrane of the infrared source is protected from harmful environmental influences. This increases the service life and reliability.

The emitter can be used with MTS thermopile detectors or with MPS pyro detectors. The combination with Micro-Hybrid IR detectors guarantees optimum performance and ensures precise measurement results for the analysis of gas concentrations.

Our sales team will be happy to advise you on customization and scale prices for high volumes. For further technical information please refer to the data sheet.
