摘要

介绍了一种高精度分光光度计系统的设计方法及其临床应用。该系统充分利用全息凹面光栅色散器件的优势

结合复杂可编程逻辑器件（CPLD）可自由编程的步进电机细分电路设计和电机定位闭环控制技术

实现了320～800 nm连续光谱范围内1 nm的高精度分光。由该系统作为核心传感部件的生化分析仪临床应用表明:系统具有连续光谱分布范围广、分光精度高、运行稳定和检测可靠等优点。

Abstract

Design method and clinical application of a high precision spectrophotometer system is introduced.The system fully uses advantage of dispersive device which based on holographic concave grating

combined with freely programmable CPLD stepper motor sub-circuit technology and closed-loop motor positioning control technology to realize the high precision spectral of 1 nm in the range of 320 -800 nm continuous spectrum.Clinical application of biochemical analyzer which based on the system as the core sensing component shows that the system has advantages

such as continuous spectrum distribution scope

high spectral precision

stable operation

reliable detection and so on.
