The USB2000+ Miniature Fiber Optic Spectrometer is a unique combination of technologies a powerful 2-MHz analog-to-digital (A/D) converter, programmable electronics, a 2048-element CCD-array detector, and a high-speed USB 2.0 port. This innovative combination produces our fastest spectrometer yet and provides resolution to 0.35 nm (FWHM). The USB2000+ allows users to capture and store a full spectrum into memory every millisecond (that's 1,000 full spectra every second) when the spectrometer is interfaced to a computer via a USB 2.0 port. The USB2000+ is perfect for chemical, biochemical and other applications where fast reactions need to be monitored.
The USB2000+ offers the following features:
- 1,000 Full Spectra/Second
- Programmable Microcontroller
- 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
- RoHS and CE compliance
The USB2000+ utilizes an onboard, 2-MHz A/D converter, which allows you to capture and transfer one full spectrum into memory every millisecond when the spectrometer is interfaced to a PC via the USB port.
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 Insight 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 Insight 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.
Users can also choose from Ocean Insight' 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.
