    Ocean Optics 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
    • 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
    • Optional Triggering Feature
    • RoHS and CE compliance

    Three Year Warranty

    ISO9001:2008 CERTIFIED
      USB2000+RAD Configuration:
