NovaIR (formerly Intex) High Pulse Rate IR Source

NovaIR (formerly 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 NovaIR (formerly Intex) IR sources use patented a-CNC films as multilayer thermoresistive elements (see below).  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 INTX22-1000 adds 40% more optical power with only a 10% increase in input power.
 

The key advantages of these pulsed sources are:
Wide Spectral Output
1 - 20 μm provides the widest emission spectrum
 
High Efficiency
With emissivity of >0.8 the spectrum is close to that of a black body

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.

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

Windows for Explosive Gases and Harsh Environments
Intex offers as an option detectors with windows for applications with explosive gasses or harsh environments

Custom Design
Intex offers custom design of IR sources

Unique technology
NovaIR (formerly Intex) IR sources are based on proprietary conducting amorphous carbon nanocomposite (a-CNC) films as multilayer thermoresistive elements. High emissivity, high thermal conductivity and low thermal mass (2 microns thick) made possible by the high strength of the a-CNC material allow rapid heating and cooling for pulsed operations at higher frequencies than can be achieved with competing technologies. The IR pulsable light sources are fabricated using MEMS technology.

Applications:

IR sources for infrared gas detectors for industrial, consumer, research and medical applications:

To avoid damaging the IR sources during soldering and cleaning, consider using Sockets.
