摘　　要：研制了一种采用线阵CCD的高速紫外可见分光光度计。报道了该分光光度计的硬件结构、软件系统设计和初步的性能测试结果。初步测试结果:波长范围2 0 0～82 0nm ,全谱扫描时间<0 1s,光谱带宽0 7nm ,波长精度±1nm ,光度精度±0 0 0 5AU ,杂散光<0 1% ,基线平直度<0 0 0 1AU(rms)。该仪器使用操作简便,测量速度快,性能优良,具有强大的光谱数据分析与处理功能,而且还独具远程操作和访问功能。预期该仪器除了可用于常规分析测试外,还适用于化学和生物等领域的动力学反应研究。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. 00 1 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.
