USB SERIES Multi purpose

/ Spectrometers

The multi purpose Spectrometers

The USB series are the world’s most popular general purpose spectrometers used in a wide range of applications and industries. USB spectrometers are highly configurable for any specific application in the UV-Vis-NIR range between 200- 1100nm. The plug-and-play operation get’s your started within minutes after installation.

The spectrometer includes the linear CCD-array optical bench, plus all the circuits necessary for spectrometer operation. The result is a compact, flexible system, with no moving parts, that’s easily integrated as an OEM component
