The USB2000+ from Ocean Optics, Dunedin, GA, is a miniature fiber-optic spectrometer that can capture and store a full spectrum into memory at 1000 scans/s. The device measures optical properties within a wavelength band of 200–1100 nm and can be equipped with a custom-selected fixed grating which disperses the light to the 2048-element CCD array detector and produces results at 0.35 nm resolution with FWHM image sharpness. Its microcontroller's digital and analog general-purpose I/O interface gives you flexibility in controlling the device and its internal EEPROM chip stores wavelength calibration. Software simplifies operation.
