WebAs a spectrophotometer is a light-based technique, it is a must to choose a steady and bright light source. Basically, the light source of the spectrophotometer should include, a) High degree and uniform brightness across the wavelength range. b) stable over time, c) long service life, and d) low cost. WebA spectrophotometer is a color measurement device used to capture and evaluate color. As part of a color control program, brand owners and designers use spectrophotometers to specify and communicate color, and manufacturers use them to monitor color accuracy throughout production.
