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 is ideal for various gas analysis applications in medicine, industry and other demanding application fields. With a very low input power of 175 mW, this infrared radiation source can also be used for mobile devices and hand held devices. The combination of filling gas and the optical window (CaF2) optimizes the emission in the wavelength range from UV to 12 µm.

The packaging version in the standard TO46 housing with reflector is suitable for measurement distances from 2 cm. 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.
