Ocean Optics - Inventor of the World's First Miniature Spectrometer

USB2000 Miniature Fiber Optic Spectrometer

The USB2000 Miniature Fiber Optic Spectrometer is a small-footprint, plug-and-play version of our revolutionary S2000 Miniature Fiber Optic Spectrometer.

Modular design
User-configured wavelength range and resolution
Automatically reads the wavelength calibration coefficients of the spectrometer and configures operating software
USB-to-PC interface; no external power requirements

The USB2000 has been replaced by the USB2000+ Spectrometer, which retails for $2639. We upgraded the USB2000 to the USB2000+ because of the limited availability of the Sony ILX511A detector used in USB2000-series spectrometers.

Facilitated Operation

Setting up the USB2000 Spectrometer is easy. The user simply installs our Spectrometer Operating Software and then connects the USB cable from the spectrometer to the computer. Wavelength calibration coefficients unique to each spectrometer are programmed into a memory chip right on the USB2000; the software simply reads these values from the spectrometer. What's more, the USB2000 requires no external power supply; it draws its power from the computer. In fact, the USB port can be used to power light sources that connect to the spectrometer.

Optimal Performance

The USB2000 couples a low-cost, high-performance 2048-element linear CCD-array detector with an optical bench that's small enough to fit into the palm of your hand -- the same detector and optical bench that have provided superior performance to the users of our 15,000 systems out in the field. The USB2000 also works the same way as other Ocean Optics spectrometers in that it accepts light energy transmitted through single-strand optical fiber and disperses it via a fixed grating across the linear CCD array detector, which is responsive from 200-1100 nm.

Modular Design

Just as with all other Ocean Optics user-configured spectrometers, users work with our applications scientists when selecting the USB2000 -- choosing from 14 gratings, 6 slits and hundreds of fiber optic accessories such as light sources, probes and optical fibers to create the optimal system for their application.

We also have a limited-time upgrade offer designed especially to enhance your UV sensing and boost UV response by over 20%. The upgrade is available for Gratings 1, 5, 7 and 10.

Users can also choose from Ocean Optics' complete line of spectroscopic accessories to use with the USB2000. Most accessories have SMA connectors for application flexibility. Changing the sampling system is as easy as unscrewing a connector and adding new components or accessories, such as light sources, sampling holders, filter holders, flow cells, fiber optic probes and sensors, collimating lenses, attenuators, diffuse reflectance standards, integrating spheres and an extensive line of optical fibers.

Optional Battery Pack

A pair of Lithium Ion cells makes the USB2000 Spectrometer field-portable. The USB-BP Battery Pack delivers 225 mA at 5 Volts -- enough juice to power a light source and the USB2000 for 8 hours continuously, or a USB-LS-450 LED module and the USB2000 for 12 hours continuously. Included is a battery charger for replenishing spent batteries.

Serial Port Option

The USB2000 also has an RS-232 serial port for interfacing to PCs and PLCs. Serial port use requires an external power supply and 9-pin serial cable (USB-ADP-PC).
