The USB2000+ miniature fiber optic spectrometer from Ocean Optics (Dunedin, FL) is designed to monitor high-speed chemical and biochemical reactions. The CCD-array detector, with a high-speed USB 2.0 port interface, can capture and store a full spectrum into memory at 1000 scans per second. The spectrometer measures optical properties within a wavelength band of 200 to 1100 nm. It can be equipped with a custom-selected fixed grating, which disperses the light to the 2048-element CCD array detector, producing results at a resolution to 0.35nm with FWHM (full width at half maximum) image sharpness.
The USB2000+ programmable microcontroller allows flexibility in controlling the spectrometer through its digital and analog general-purpose input/output interface, and it can be used in various trigger modes. The internal nonvolatile EEPROM memory chip stores the wavelength calibration to be automatically used by the operating software.
