Boston Electronics offers a broad selection of infrared (IR) sources / emitters for wide range of applications. We carry emitters from the leading suppliers of steady state and modulated (pulsable) sources, namely HawkEye Technologies, Helioworks and FLIR Systems (end of life). All produce devices that are robust, proven and affordable.

Complementing our line of IR emitters are our infrared detectors, and universal photon source driver (UPS) electronics, a powerful, flexible driver to allow you to easily use the range of sources we provide

Typical applications for our emitters include;

  • Spectroscopy/ non-dispersive infrared spectroscopy (NDIR)
  • Medical (CO2 / other gases monitoring, breath /vapor analyzing)
  • Military / Law Enforcement (beacons, IFF)
  • Automotive / Transportation (breath alcohol testing / exhaust monitoring)
  • Aerospace (calibration systems, image sensing)
  • HVAC (demand controlled ventilation, refrigerant monitoring)
  • Safety / Industrial / Environment Control (combustion gas analyzers, gas detection, air pollution)

We have three types of electrically modulatable IR thermal sources. These are:

  • Filament sources from HelioWorks, HawkEye, and Heimann
  • Diamond-like film sources from HawkEye and Heimann
  • Metallic foil sources from HelioWorks

See our catalog below for the range of solutions we offer and if you have questions speak with our applications staff to discuss your requirements.  Also, visit our web store to easily purchase the devices you need.

HawkEye Technologies

For 40 years HawkEye Technologies has been an industry leader in the manufacture of high quality standard and customized IR thermal emitters featuring true blackbody radiation characteristics, low power consumption, high emissivity and a long lifetime.

The broadband steady state and electrically modulated (pulsable) IR thermal sources supplied by HawkEye Technologies produce a broad spectrum of IR light from 1 to 20 µm (mid-infrared) depending upon the operating temperature of the device. HawkEye has developed a proprietary line of reflectors to maximize the performance of the emitters and offers a variety of windows to achieve the desired effect.


HelioWorks, Inc. manufactures a wide range of sources primarily for the OEM market. Infrared sources from HelioWorks include pulsable sources utilizing Tungsten and Nichrome (NiCr) and steady state sources utilizing Kanthal and Tungsten filaments. All are constructed in industry standard TO-3, TO-5 and TO-8 sized packages with gold plated parabolic reflectors to enhance output in the near infrared.

FLIR Systems

July 2018 Note: FLIR sources have gone end-of-life.  Please ask us about remaining availability, and substitute products from HawkEye and HelioWorks. 

There is some remaining inventory which is available in the web store.
