FAST-SCANNING SPECTROPHOTOMETRY SYSTEM USING A NEW COMPENSATORY MODEL

It is necessary for a modern spectrophotometry system to possess such properties as high measuring accuracy, fast working speed, uniform spe ctral response in the whole wavelength band, low consumption of power, little heat accruing while working, small size and low weight, etc. T o meet all these needs, a spectrophotometry system today usually emplo ys the so-called dual-beam channel configuration in which one sampling channel with another compensatory channel and a cold light source suc h as a xenon flash lamp, which usually causes an increase of the compl exity in the system configurations. To further simplify the instrument configuration, we put forward a new dual-channel compensatory model c alled the integral compensatory model. Our experimental results show t hat using this new model, a spectrophotometry system cannot only be gr eatly simplified in its hardware but can also achieve highly accurate measurements.
