Light Sources

Many spectroscopy applications require a source of illumination or, in the case of applications like fluorescence, excitation energy. Avantes offers a wide selection of light sources designed for compatibility with the AvaSpec modular platform and to deliver the appropriate wavelengths to suit your application needs. Sources include continuous wave tungsten-halogen, deuterium halogen, pulsed Xenon as well as LEDs and calibration lamps.
