New! USB Light Source - Emission Line Source for Intelligent Spectrograph Calibration This compact light source features high stability and produces spectral lines necessary for wavelength calibration. Mercury has widely spaced emission lines ranging from 253.65nm to the 576.96 & 579.07 nm doublet, while Ar and Ne cover the visible and NIR range. This quasi-CW USB-powered source includes both mercury and neon-argon lamps mounted in a flange that matches the slit body of the Acton Series and similar spectrometers. Designed to work with IntelliCal software. Download the datasheet

Deuterium Light Sources

Model DS-421: 30-watt light source, 110 V, provides useful UV continuum starting at ~190 nm and continuing out to ~350 nm. Negligible visible light output helps to minimize stray light. Model DS-421-220: Same as DS-421, for 220 V.

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

Model TS-425: 30-watt, 110 V light source with a DC power supply.

Model TS-425-220: 30-watt, 220 V light source with a DC power supply.

Model TS-428: 250-watt, 110 V light source, includes variable brightness control, forced-air cooling, and AC power supply.

Model TS-428-DC: 250-watt, 110 V light source features a regulated DC power supply plus variable brightness control. 

Model TS-428-220: 250-watt, 220 V light source includes variable brightness control, forced-air cooling, and an AC power supply.

Model TS-428-DC-220: 250-watt 220 V light source features a regulated DC power supply plus variable brightness control. 

Model XS-433: 75-watt, 100 V 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.

Model XS-433-220: 75-watt, 200 V 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 Sources

Model TDS-429: combines 30-watt, 110 V 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, power supplies, and forced-air cooling fan.

Model TDS-429-220: combines 30-watt, 220 V 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, power supplies, and forced-air cooling fan.
