Spectrometer
Light source
Sources for illumination cover the UV and VIS-NIR ranges to enable absorbance, reflectance and transmission measurements. Compact LEDs produce pulsed or continuous output for fluorescence measurements. And for fast, reliable calibrations, our HG-1, LS-1-CAL and DH-2000-CAL cover the 253-922 nm, 300-1050 nm and 220-1050 nm ranges respectively.
Modular Light Source Options
| Type | Usage |
| Tungsten Halogen Light Sources: | Used most often as standard VIS-NIR light sources for absorbance, reflectance of solid objects and color measurement. |
| Deuterium Light Sources: | Used most often for UV absorbance and reflectance measurements, and for applications requiring a stable, high-power source. |
| Combination UV-VIS-NIR Light Sources: | Used as a single illumination source for measurements across our spectrometers' entire wavelength range. |
| Pulsed Xenon Lamp: | Used most often in applications requiring a long-life light source for absorbance, reflectance and fluorescence measurements, and for measuring optically or thermally unstable samples. |
| Light-emitting Diodes: | Used most often as an excitation source for fluorescence applications. Features minimal warm-up time and high stability. |
| Mercury-Argon Wavelength Calibration Source: | Used as a wavelength calibration source for spectrophotometric systems. Produces Hg and Ar atomic emission lines from 253-922 nm. |
| Calibrated Tungsten Halogen Light Source: | Used to calibrate the absolute spectral intensity of a system. Its spectral intensity is NIST-traceable. |
