Spectroscopy Applications

Spectroscopy Light Sources

Mercury Light Source 
Model MS-416: compact light source that features high stability and line output useful for wavelength-calibration purposes. There are many lines produced by mercury, including 253.7-nm, 313.1-nm, 365-nm, 435.8-nm, 546.1-nm, 577-nm, and 579-nm wavelengths. This source includes a mercury lamp mounted in a flange that matches the slit body of the Acton Series, SpectraPro® and similar type spectrometers, plus a power supply.

Deuterium Light Source
Model DS-421:  30-watt light source that provides useful UV continuum starting at ~190 nm and continuing out to ~350 nm. Negligible visible light output helps to minimize stray light.




Tungsten-Halogen Light Sources
are light sources for 350 nm to 2.5 µm.

  • Model TS-425: 30-watt light source with a DC power supply.
  • Model TS-428: 250-watt light source that includes variable brightness control, forced-air cooling, and an AC power supply.
  • Model TS-428-DC: 250-watt light source that features a regulated DC power supply plus variable brightness control. 

Xenon Light Source
Model XS-433: 75-watt light source that features broad wavelength output with small source size, permitting more efficient light delivery to a spectrometer. This source provides useful continuum from 190 to 750 nm, with declining output out to 2.7 µm.

Deuterium and Tungsten-Halogen Dual Light Source
Model TDS-429: combines 30-watt deuterium and tungsten-halogen lamps in the same housing for output useful from 190 nm to 2.5 µm. It includes a manually controlled source-selection mirror (motorized optional), power supplies, and forced-air cooling fan.
