Colorimeter
Principle of Colorimeter. When an incident light beam with intensity I 0 passes through a solution, a part of the incident light is reflected (I r) and absorbed (I a) while the remaining incident light is transmitted (I t).. i.e., I o = I r + I a + I t. The measurement of (I 0) in the colorimeter eliminates (I r), and it is sufficient to calculate the (I a).
