Photometric distribution types

WebPhotometry is the science of the measurement of light, in terms of its perceived brightness to the human eye. [1] It is distinct from radiometry, which is the science of measurement … WebThe three types of photometric measurement instruments: 1. Colorimeters use colored filters to isolate light of a specific wavelength which is passed through the test sample. Since colorimeters generally test for a single ion, the wavelength of light that is passed through the test solution is selected to identify that particular ion.
