It is important to select a proper light source according to the specific measurement in spectroscopic applications. Spectral Products offers wide range selection of light sources for various applications.

Broad-band light source:
Broad-band light sources are needed for transmittance, absorption and reflectance spectroscopic measurements.

• Tungsten-Halogen (TH):
  TH is a general light source for visible and NIR range spectroscopic applications.
• 5W fiber coupling TH light source
• 20W fiber coupling TH light source
• 30W high stability TH light source
• High power TH series
• Deuterium (D2):
  D2 is a general light source for UV range spectroscopic applications.
• 30W deep UV single/dual D2 light source
• Xenon (Xe):
  Xe is a general light source for UV, visible and NIR range spectroscopic applications. The spectrum curve in visible range is relatively flat compared to other light sources.
• 175W fiber optic light source
• IR Emitter (CFIR):
  CFIR is a general light source for IR range spectroscopic applications.
• Coiled filament IR emitter
• Hybrid:
  By the combination of a deuterium lamp and a tungsten-halogen lamp, the whole spectral range from deep UV to NIR (185-2500nm) can be covered.
• Miniature type D2 and TH hybrid light source
• Single 30W D2 and high power TH hybrid light source
• Dual 30W D2s and high power TH hybrid light source
• Uniform/Diffused:
  With an integrating sphere, any light source can generate an uniform output.
• 1.5" integrating sphere with built-in 5W TH light source
• General diffuse light source

Narrow-band light source:
In general, narrow-band light sources are used as excitation sources. In some wavelength ranges that lasers cannot cover, narrow-band light sources are very useful. Some atomic emission lamps are used as reference standards for wavelength calibration in spectroscopic applications.

• Wavelength tunable light source:
  With the combination of a monochromator and a broad-band light source, continuously tunable, narrow-band wavelength light can be acheived. The bandwidth depends on the slit width and the grating groove density used in the monochromator (~1-20nm, typically).
• Tungsten-halogen based tunable light source
• Deuterium based tunable light source
• Xenon based tunable light source
• D2 & TH Hybrid based tunable light source
• Other broad-band light sources can be used. Please call 860-928-5834, ext 13/17 (Connecticut) or email jpark@spectralproducts.com / sales@spectralproducts.com.
• Calibration light source:
  Depending on the gas filled in a lamp, discrete spectral lines of defined wavelength, spectral width and relative instensity can be obtained.
• Spectral calibration light source assembly
• Portable spectral calibration light source
• Discrete wavelength excitation light source: COMING SOON!!
  Based on the combination of materials, some defined wavelength light is generated. With a proper focusing lens, high power density light can be obtained at a certain focus. This light source is for fluorescent applications.
