1 Electro Optical Components, Inc Skylane Boulevard, Santa Rosa, CA 9543 Toll Free: 855-EOC-63 Application Note 2/9 technical description of JSIR45 The JSIR45 is a wide band and powerful Infrared-Source. It has a big radiation power in the IR-band up to 5µm. In contrast to glow spiral emitters a circular homogeneous temperature distribution is reached. The JSIR45 has a broad spectral range output with high intensity. A high electric power consumption is possible within long lifetime. The JSIR45 works e.g. in infrared spectroscopy, gas detection systems, air quality and environment monitoring and in medical gas monitoring.

2 Variations and Accessories: The JSIR45 is offered in two versions. With a TO39 cap as a handling protection or with a parabolic reflector cap. In addition, a puttable on cap reflector can be ordered for the TO39 cap. The ray density could be raised by using a reflector around the 6-fold.

4 Additional information about the JSIR45 Frequency-responce: Modulation Depth vs. Frequency Modulation Depth.... Modulation Frequency [Hz] Temperature The JSIR45 has the typical spectrum of a black emitter. The spectral intensity distribution depends on the temperature of the heating element which can be adjusted by the electric input power. A regular circular temperature distribution on the heating element is reached by special structuralisation.
