USB2000+RAD Spectroradiometer
for Irradiance Measurements
The USB2000+RAD Spectroradiometer is a preconfigured combination of a powerful 2-MHz analog-to-digital (A/D) converter, programmable electronics, a 2048-element CCD-array detector, a high-speed USB 2.0 port, and cosine corrector. This innovative combination produces our fastest spectrometer yet and provides resolution to 0.35 nm (FWHM). The USB2000+RAD 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+RAD is perfect for chemical, biochemical and other applications where fast reactions need to be monitored.
This spectroradiometer system features a USB2000+ Spectrometer and attached CC-3-DA cosine corrector that does not require in-field NIST-traceable UV/VIS/calibration since it has been precalibrated by Ocean Optics with our SPEC-CAL-UV radiometric calibration service for UV spectrometers. The USB2000+RAD is preconfigured and is ready for measurement out of the box?so that installation and measurement is fast, accurate and convenient.
The USB2000+RAD 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
1,000 Full Spectra/Second
The USB2000+RAD 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.
Programmable Microcontroller
The USB2000+RAD 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+RAD 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.)
Facilitated Operation
Setting up the USB2000+RAD 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+RAD 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+RAD 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+RAD 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.
