WebPhotometers are often used to measure chemical reactions, like changes in the acidity (pH) of a solution, by measurement of the intensity of an indicator dye. For optimal detection you may want to measure only the absorption of light close to the absorption maximum of the dye. Therefore you will prefer to use a monochromatic light source ... WebFeb 11, 2024 · A photometer indicates the photoelectric detector that measures the intensity of light. Spectrometer: It produces the desired range of wavelengths of light. First, a collimator (lens) transmits a straight beam of light (photons) that passes through a monochromator to split it into several component wavelengths (spectrum).
