SANTA ROSA, CA - INTEX has developed a series of miniature pulsed infrared (IR) light sources with high intensity and ability to pulse at high frequencies. Their emission spectrum is that of a gray body.  The INTEX IR sources use patented a-CNC films as multilayer thermoresistive elements.  The a-CNC’s durability makes it possible to have a 2 micron thick element with very low thermal mass that allows rapid heating and cooling for pulsing at higher frequencies than any other technology can do. The key advantages of these pulsed sources are:

• Wide Spectral Output - 1 - 20 µm
• Fast Response - These IR sources can be modulated at a frequency of over 100 Hz because the sources' membranes are only 2 microns thick with very low thermal mass.
• High Efficiency - With emissivity of >0.8 the spectrum is close to that of a black body.
• Operates at Higher Temperatures - Achieves its efficiency by operating at a higher temperature than competing technologies.
• Long Life and Cost Effective - With a lifetime of up to 25,000 hours and absence of any need for separate modulation, maintenance and product cost are reduced.

Intex manufactures high quality pulsable IR sources for use with pyroelectric and lead selenide (PbSe) detectors gas analysis for applications including Medical, Refinery, Mining, Automotive and Semiconductor Instrumentation.
