👉 A spectrophotometer is a device used in spectroscopy to measure the intensity of light, which can be converted into a visible spectrum. These spectrophotometers consist of an optical system that allows light to pass through it and then to convert this light into an electrical signal that can be measured by a meter or other instrument. In the context of spectrometers, a spectrobolometer is a device designed for spectroscopic applications where the light intensity is measured directly. It uses a light
