A colorimeter is a device used to measure the absorbance or transmittance of a specific color or wavelength of light, usually used for determining the concentration of a particular substance. It contains a filter that only allows light of a specific wavelength to pass through, which is then detected and measured. On the other hand, a spectrophotometer measures the entire spectrum of light that is absorbed or transmitted through a sample. It does not use filters, instead it separates the light into different wavelengths using a diffraction grating or prism. This allows for the measurement of the intensity of light at each wavelength, and can be used to identify different compounds based on their unique absorption spectra. In summary, a colorimeter is best suited for measuring specific colors or wavelengths, while a spectrophotometer is more versatile and can analyze the entire spectrum of light.
