EOC supplies a wide range of infrared lamps primarily for the OEM market. Their products are used in near infrared (NIR) spectroscopy, non-dispersive infrared (NDIR) gas detectors for medical and industrial applications including: CO, CO2, alcohol, hydrocarbon and other noxious gases, thermal reference calibration, thermal markers, thermal beacons, and many other applications.
Check the high efficiency Nanostructure IR Sources with a near black-body emittance. They are high power and also available in SMD packaging.
PULSABLE sources utilizing tungsten and Nichrome (NiCr) and STEADY STATE sources utilizing Kanthal and NiCr filaments 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.

| Basic Series (with Integrated Reflector) | |||||||||
| The Basic Series emitters have an integrated gold plated reflector that directs the radiation emitted from the rear to the front to achieve maximum efficiency and optical output power. The IR emitters are characterized by a very low temperature coefficient of electrical resistance. The electrical control of the infrared sources is easy, as the hot and cold resistances are almost identical. | |||||||||
