USB2000+UV-VIS and USB2000+VIS-NIR Miniature Fiber Optic Spectrometers

The USB2000+ Series of Spectrometers from Ocean Optics feature an amazingly small footprint, plug-and-play capabilities and a simplified interface that operates without external power.

Simply plug your USB2000+UV-VIS or VIS-NIR into an available USB port on your computer and you eliminate the need for analog converters.

Your spectrometer comes preconfigured to the 200-850 nm wavelength range for USB2000+UV-VIS or 350-1100 nm for the USB2000+VIS-NIR. Both models include a proprietary multi-bandpass order sorting filter. Our USB2000+UV-VIS also features a UV2 detector coating upgrade.

Our ES (Enhanced Sensitivity) models feature an installed detector collection lens for increased light collection efficiency.
