• Deuterium (D2)

  D2 is a general light source for UV range spectroscopic applications. D2 lamps produce intense ultraviolet radiation by maintaining a stable electric arc in a deuterium atmosphere. The spectral power distribution of this radiation has a continuous range that extends from 160 to 400 nm (D2 spectrum). This continuous and stable characteristic of the arc makes deuterium lamps the most useful source of UV for analytical instruments, including spectrophotometers, liquid chromatography detectors, medical analyzers, pollution analyzers, colorimeters, and densitometers. Because of the stability and reproducibility of deuterium lamps, they are suitable as secondary calibration standards in the ultraviolet region.

• 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. The 175W Xe light source (Xe spectrum) is a compact and light weight high intensity light source. It is especially suitable as a light source for spectroscopy, microscopy, optical scanning, and industrial uses, as well as for use with SP's popular Digikröm monochromators and spectrographs. According to the bulb type, it can cover ~185-2200nm (dominantly, ~250-1100nm), ~320-2200nm (dominantly, ~320nm-1100nm) and ~320-700nm.

• 175W fiber optic light source

• IR Emitter (CFIR)

  CFIR is a general light source for IR range spectroscopic applications. The coiled filament operates at approximately 975°C when powered with 11 watts (ASB-IR-12K). The radiating element is a coil of resistance wire which has a high emissivity in the Infrared spectral region (1.0µm ~ 30.0µm). The coil is supported on a grooved cylindrical substrate of alumina, resulting in the windings being electrically insulated from each other and this contributes to a more uniform radiating source.

• 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.

• Uniform/Diffused

  With an integrating sphere, any light source can generate an uniform output.

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).
