What Do Single and Double Beam Spectrophotometers Do?
A single and double beam spectrophotometer is an instrument which is designed to measure light by wavelength distribution. There are a wide variety of different sizes and styles of spectrophotometers both single and dual beam, with their size and configuration largely dependent on the specific applications for which they are designed. A single beam instrument is used to measure the intensity of a beam of light before and then after the addition of a sample and uses a light source, a prism and a photocell as well as a sample holder for the material being analyzed by means of spectrophotometry. Spectrophotometer single beam or double beam models offer the ability to control the wavelength and intensity of the light source. The results provided by these instruments are in the form of voltage fluctuations which are the light energy received by the photo cell into the form of electrical energy, which is then displayed and/or recorded on a connected computer for further analysis.
