The products include PULSABLE sources utilizing tungsten and Nichrome (NiCr) and STEADY STATE sources utilizing Kanthal and NiCr filaments. All are constructed in industry standard TO-5 and TO-8 sized packages with gold plated parabolic reflectors to enhance output in the near infrared. We welcome your requests with specialized requirements to meet your needs.
 
The EF-853X Series is a high quality replacement for the old SVF-series emitters. The EF-853X Series infrared (IR) emitters are designed to be used as pulsable sources of blackbody radiation. The radiating element in the pulsable emitters is an ultra-thin metallic foil configured so that radiation from both sides of the heated foil is efficiently directed out of the package along the optic axis. The foil material has an emissivity of 0.88 and closely emulates a blackbody source in spectral distribution.
 
Key Features
  • Pulse or steady state
  • Long term stability
  • Desirable signal-to-noise ratio
  • Large temperature modulation, ΔT, in pulse mode
  • Latest technology in packaging and window options
  • Internal gold plated parabolic reflector. Gold has a very high reflectance in the near infrared. This reflectance is several percent greater than polished aluminum which is typically used in conventional infrared sources.
