Answer :
Total incident light shining on the cuvette is the parameter that the spectrophotometer's detector measures directly.
A spectrophotometer is a device used to gauge electromagnetic radiation strength at various wavelengths. The spectrophotometer measures the light intensity of a sample by passing a light beam through it. The following are some of the parts of a spectrophotometer:
Light Source: The spectrophotometer needs a light source to produce lights.
Lens collimator:This lens directs the light from the light source to a monochromator or prism.
Detectors: These are photosensitive tools, like photocell detectors, that generate current proportional to the amount of light that strikes them.
