USB2000+ fast gated CCD array spectrometer

 Miniature Fiber Optic Spectrometer

The USB2000+ Miniature Fiber Optic Spectrometer is all about speed -- a powerful 2-MHz analog-to-digital (A/D) converter, programmable electronics, a 2048-element CCD-array detector that is gateable, and a high-speed USB 2.0 port. The USB2000+ captures a full spectrum into memory every millisecond  when the spectrometer is interfaced to a computer via a USB 2.0 port. This fast, gateable array is ideal for use in pulsed laser induced emission applications like LIBS and phosphorersence, as well as routine use for absorbance, reflection, or flourescence measurements.

1,000 Full Spectra/Second

  • Gating

  • 1,000 Full Spectra/Second

  • Programmable Microcontroller

  • Modular design

  • User-configured wavelength range and resolution

  • Plug n Play -- Automatically reads the wavelength calibration coefficients of the spectrometer and configures operating software

  • USB-to-PC interface; no external power requirements

  • RoHS and CE compliance

  • Rugged, reliable work-horse unit of the OOI product line

The USB2000+ has an onboard programmable microcontroller that provides flexibility in controlling the spectrometer and accessories. Through a 20-pin connector, you can implement all operating parameters in the software, such as controlling external light sources, creating processes and routines and retrieving data from external devices. The USB2000+ gives you access to 10 user-programmable digital I/Os for interfacing to other equipment; one analog input and one analog output; and a pulse generator for triggering other devices. (Programming the I/Os requires SpectraSuite Spectroscopy Operating Software.)

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. 

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 90,000+ 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.

Just as with all other Ocean Optics user-configured spectrometers, users work with our applications scientists when selecting the USB2000+ 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
