Flexible Design, Great Performance
OneFocus Advantage
Features
• Great response across the 200-1100 nm wavelength range
• Hundreds of configurations possible with modular design
• Built-to-suit wavelength range and optical resolution performance
• High-speed electronics for capturing and storing up to a thousand spectra per second
The USB2000+ is a modular spectrometer. You can select a model that is preconfigured
for a particular application or you can build your own. Our Application Sales Engineers
help you with selection of grating, slits and optical bench accessories, as well as
sampling accessories such as fibers, light sources, sampling holders, filter holders, flow
cells, fiber optic probes and integrating spheres.
At the heart of the USB2000+ is a 2048-element CCD array detector in a robust,
high-speed optoelectronic design that provides remarkable performance for a
spectrometer its size. Depending on configuration, sub-nanometer optical resolution is
possible, and rapid acquisition rates allow users to capture and store up to 1,000 full
spectra every second. Also, the spectrometer’s detector has a UV-sensitive coating that
makes the system versatile enough for UV-Vis and Vis-NIR performance.
Absorption bands of atmospheric elements are easily identifiable in this solar irradiance
spectrum measured with a USB2000+ spectrometer and cosine corrector.
