    Abstract: In the measurement of the optical transmittance of a sample, a beam which is split from a source of illumination is . directed through the sample and then redirected back through the sample. The redirected beam and a reference beam which is also split from the source of illumination are alternately applied to a photodetector. Both the sample beam and the reference beam pass through a monochromator prior to application to the photodetector. The output of the photodetector is processed by an electronic circuit and applied to a computer. Data representative of the two beams can be compared in order to provide an indication of the amount of light the sample transmits at certain optical wavelengths.
