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
