摘　　要：结合国家九五攻关"全自动生化分析仪的研制与开发"项目,研制了一种用于全自动生化分析仪的紫外 可见分光光度计。该分光光度计采用全息凹面平像场光栅为分光元件,以硅光电二极管阵列为探测器。光度测试采用后分光技术,从光源辐射的复合光先经样品溶液吸收后再由全息凹面平像场光栅分光,光电二极管阵列同时接收12路光谱信号,多个光谱信号同时检测,实现快速测量。Spectrophotometer is one of the key components in a full-automatic biochemical analyzer and it has its direct effect on the accuracy of the entire system. An ultraviolet-visual spectrophotometer has been developed for full-automatic biochemical analysis by using holographic aberration-reduced grating as spectroscope and photoelectron diode array as detector. Composite light coming from lamp-house is absorbed by sample solution first and then illuminated to the surface of the concave holographic aberration-reduced grating. The photoelectron diode array can receive 12 beams of light signal at the same time for fast measurement, and this is why it is referred to as back-dividing-light technology
