Spectrophotometer has a monochromator (for seperating the individual wavlengths of light) and is a scanning instrument. WebA photometer measures relative rather than absolute intensity. The Bunsen photometer (named for R. W. Bunsen) determines the light intensity of a source by comparison with a known, or standard, intensity. The two light sources (one of known, one of unknown intensity) are placed on opposite sides of the surface (a disk of paper) to be illuminated. can cricut mats be cleaned
