UV-Vis-NIR Light Sources

UV-Vis-NIR light sources for illumination use xenon, deuterium and tungsten halogen to cover various wavelength segments from 200-2500 nm. Use sources for absorbance, transmission, reflectance and more.

Visible and NIR Light Sources

Krypton and tungsten halogen sources are available for measurements from 360-2500 nm. These white light (broad bandwidth) options are ideal for absorbance, color and reflectance.

LEDs

LSM LEDs provide efficient coupling of LED light into optical fibers, ensuring high signal output. A programmable driver-controller enables monitoring of LED power output, temperature and more.

Raman Lasers

High power lasers are available for Raman excitation wavelengths of 532 nm, 638 nm, 785 nm and 1064 nm. These multimode diode lasers produce narrow spectral lines and have integrated laser drivers.

Calibration Sources

We offer two types of calibration sources: gas-discharge emission sources for spectrometer wavelength calibration; and radiometrically calibrated sources to calibrate the absolute spectral intensity of irradiance systems.
