If desired, color spectrophotometers can be used to calculate psychophysical colorimetric information as well. Spectrophotometers are
Principle of Colorimetric Spectrometer
A colorimeter operates based on the Beer-Lambert Law, which posits that the absorption of light by a solution is directly proportional to the concentration of the absorbing substance and the path length of light. When incident light (I0) passes through a solution, some of it is reflected (Ir), absorbed (Ia), and transmitted (It), following the equation I0 = Ir + Ia + It. By measuring I0, the. Spectrophotometers and Colorimeters are both used to accurately measure colour, which is important in some scientific processes and also for matching colours for commercial production of products where colour accuracy is essential. The instrument mainly. In photometers (colorimeter & spectrophotometer),...
