USB Series Spectrometers

Summary of USB Features and Benefits

usb2000+Modular USB spectrometers are versatile, general-purpose UV-Vis-NIR spectrometers for absorption, transmission, reflectance, emission, color and other applications. Their compact size, robust optoelectronics and easy modularity make them the most popular spectrometers in the world, supporting thousands of applications, from research and life sciences to education and materials identification.

The USB Series comprises USB2000+ and USB4000 models. The models are available in custom configured and preconfigured options. OEM configurations are also available.

Custom Configured USB Series Spectrometers

When you select a custom configured spectrometer, we work with you to design the optimum configuration for your measurement. We assemble the optical bench components including gratings, slits and filters to deliver the performance your application demands. Our Application Sales Engineers guide you through your experiment and help you choose the correct components.

The USB2000+ and USB4000 are both good choices for a range of applications, but there are some differences among the two:
