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).

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.

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. 

Optional Triggering Feature

We now offer triggering functions with our USB2000+ to provide accurate timing and synchronization between your spectrometer and other devices. Four low-jitter trigger modes and normal (free-running spectral acquisition) operating modes are now possible. Read more about triggering here.

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 150,000+ 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.

USB2000+RAD Configuration

The USB200+RAD is preconfigured with the following, along with an CC3-DA cosine corrector, SpectraSuite spectrometer operating software, SPEC-CAL-UV radiometric calibration service, and our Annual Service Package (ASP):

Serial Port Option

The USB2000+RAD 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).
