Development and status of on-line spectrophotometer

Abstract

The principle of color measurement is introduced,and the characteristics requirements and technical difficulties of on-line color measurement are summarized. The development process and the current state of the art of on-line color measurement technology are also presented. The specifications,applications and system structures of several advanced on-line spectrophotometes abroad are presented in detail. The characteristics and advantages of every instrument are highlighted. The development trend of on-line spectrophotometer is discussed from two aspects of technical perspective and application requirements in this paper,which will provide a reference for study on the development of on-line spectrophotometer.
