Miniature Fiber Optic Spectrometer is a portable instrument for rapid spectral analyzing. The device is powered by USB 2.0 interface, very suitable for the application of chemical, biological and other applications that require on-site monitoring. The device is composed of fast 16-bit analog to digital (A / D) converter, 2048-pixel CCD array detector and a high-speed USB 2.0 interface. Integration time of the spectrometer is from 1ms to 30s. A thousand frame data can be transmitted from hardware to PC in a second in shortest integration time. At the same time, with the outstanding circuits and optical design, resolution (FHWM) can up to 0.35nm (depend on the width of the slit).
