👉 A spectrophotometer is a device used for measuring the absorbance of light. It consists of a light source and an optical system that focuses or diffracts the light, allowing it to be measured with high accuracy and resolution. The light source can be a laser or a cathode ray tube (CRT) that emits light in a specific wavelength range. The optical system includes a filter that allows only certain wavelengths of light to pass through, while other wavelengths are blocked by the filter. This
