UV Deuterium Light Source (200 - 400 nm): STN-SL3 (Stellarnet)

StellarNet has a variety of UV light sources available for spectroscopy applications. Ultra-violet light interacts with many types of molecules and samples and thus finds use in environmental studies, biological applications, chemical processing, and many other applications.

The STN-SL3 Deuterium Light Source emits a deep UV spectral output over the 190-450nm range and higher. When using StellarNet STN-BLACK-Comet concave grating spectrometers, you can perform spectroscopy applications past 550nm.

High Output Power: With over 15 Watts/m^2 the STN-SL3 is one of the brightest compact UV light sources available. It can be used for absorbance, transmission, fluorescence, and even reflectance spectroscopy.

Long Life: 2,000 hour performance due to special air flow design and ultra quite fan operation. Customer reports of continuous operation for over a year!

Exceptional Performance: designed for maximum stability with precision power control. it is ideal for UV spectroscopy

Portability: small size allows for use in field or mobile spectroscopy applications.

Popular Systems that use UV Deuterium STN-SL3 lamp: UV-VIS Absorbance, Fluorimetry, UV SpectroRadiometry, Calibration Sources
