Sources for Illumination, Excitation, Calibration

Our light sources for illumination, excitation and calibration cover various wavelength ranges to enable absorbance, transmission and reflectance measurements from the deep UV to the mid-IR.

UV Sources
We offer deuterium sources for UV absorbance and reflectance measurements. Our pulsed xenon lamps are long-life sources for absorbance, reflectance and fluorescence measurements -- and for measuring optically or thermally labile samples.

Combination Sources
Our combination deuterium and tungsten light sources are used as single illumination sources for UV-NIR measurements.

VIS-Mid-IR Sources
Tungsten halogen sources are standard VIS-NIR sources for absorbance, reflectance of solid objects and color measurement

High-Powered LEDs
Used as excitation sources for fluorescence, our LEDs feature minimal warm-up time and high stability. Power requirements are lower and spectral width is wider than with lasers.

Radiometrically Calibrated Light Sources
Used to calibrate the absolute spectral intensity of a system in irradiance applications.

Wavelength Calibration Sources
Used to calibrate the wavelength of spectrophotometric systems. We offer a full range of options for your UV-VIS needs.
