Abstract：A high speed spectrophotometer based on a linear CCD was developed. The function and structure of the hardware and the software for the instrument were discussed. The elementary performance was tested as follows: wavelength range 200-820 nm, full spectrum scan time ＜0.1 s, spectral bandwidth 0.7 nm, wavelength accuracy ±1 nm, photometric accuracy ±0.005 AU, baseline flatness ＜0.001 AU(rms), and stray light ＜0.1％. Results showed that this instrument is easy to use, fast and with high analytical performance. In addition, it has internet function of remote control and remote access. With the powerful data processing and spectrum analyzing software, it will provide a strong tool for routine analysis and the research on dynamic reaction in chemistry and biology fields.
