What is a Colorimeter?
A Colorimeter is an instrument used to measure light reflected or transmitted by a specimen.
There are two general types of colorimeters commonly used: (1) for measuring concentrations of color matericals for anaylitical purposes, and (2) for measuring quanitites which can be correlated with a psychophysical description of color. Generally, the second type should properly be referred to as a tristimulus colorimeter.
