What is the difference between a spectrophotometer and a photometer? A photometer simply measure the total lumens of a light source, while a spectrophotometer will measure a whole spectral of that same light source.
Spectrophotometer A spectrophotometer is an instrument that measures the amount of light that can pass through a solution. It is apparent that less light is allowed to pass through a highly turbid or colored solution than through a clear solution. Spectrophotometer is the device that can quantify the amount of light transmitted through solutions. Inside a spectrophotometer, light is focused through a lens system to an entrance slit.
