Abstract
The electronic photometer of a recording spectrophotometer is described in detail. Sources of error of the circuit and experimental measurements of the inherent noise of the system are discussed. A segmented diode circuit is described for converting data in absorption to units of optical density with an accuracy of better than 1 percent. The electronic circuit of the servo system to correct the nonlinearity of the wavelength scale is also described.Keywords
