Thermal Sources

NEW!! - You spoke and we listened.

Now available is the Universal Photon Source (UPS) Driver Board that drives infrared sources, LEDs, and lasers in CW or pulsed mode.  Click here for information.

 

-------------------------

Miniature, CW 1100K and 1275K IR blackbody sources

Our standard wirewound filament sources have an emissivity of ~0.8 and are available in 4-watt, 8-watt, and 13-watt versions. The coil is wound on an alumina ceramic cylinder. Operation in a controlled or sealed atmosphere is not required.  The 1100K 8-watt version is also available in a mechanically identical 1325K version drawing about 13 watts. 

The following resources provide additional information on the infrared sources.

Electrically modulated IR sources

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

  1. Filament sources in TO-8 packages from Helioworks
  2. Diamond-like film sources from HawkEye
  3. Metallic foil sources from FLIR
  4. Silicon-based photonic crystal sources from FLIR.

Diamond-like films from HawkEye:

The IR-5x series can be modulated electronically to 100 Hz.  Details HERE.

Metallic foil sources from FLIR:

Electrically modulated IR sources in TO-5 and TO-8 packages.   In general, these devices are useful with pyroelectric and thermopile detectors optimized at frequencies < 10 Hz.

Gas analysis is the usual application of these devices.

Silicon-based photonic crystal sources from FLIR

These are silicon MEMS devices whose emissivity has been modified by surface structure control so that they emit selectively in the spectral region of interest.  Currently available are devices with emission surpressed except in the 3-5 or 8-14 micron ranges.  The result is improved 'wall plug' efficiency compared to gray-body emitters like most of the souces we offer.  Click here for details on these devices, called TunIR restricted band IR sources.
