Premier Manufacturer of Specialized Infrared Lamps
and Creator of Innovative IR Sources and Infrared Emitters.
We manufacture a wide range of infrared lamps primarily for the
OEM market. Our 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.
Our 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-8 sized packages with gold plated parabolic
reflectors to enhance output in the near infrared. Additional products are being developed. We
welcome your requests with specialized requirements to meet your
needs.
High Temperature Infrared Emission
Helioworks has developed state-of-the-art incandescent IR sources utilizing tungsten filaments for high temperature, stable, and long life operation. Pulsable versions feature large temperature
modulation at elevated frequency. We have broad capability in
the design of steady state and pulsable sources utilizing both
tungsten and Kanthal filaments. If our standard models do not
meet your needs, please let us know your requirements.
Tungsten filaments are used in most common incandescent light bulbs but these have glass envelopes that do not transmit infrared in quantity. Tungsten achieves the highest temperature and power of any practical material and is therefore
a valuable source of infrared emission at longer wavelengths.
However, to make a source of intense infrared emission using tungsten,
one must use another protective window and we have chosen sapphire
because of its high transmission in the near infrared. The uniqueness
of our product is the integration of the sapphire window with
the tungsten filament. This allows high power transmission in
the near infrared.

Another innovation these sources have is an 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.
