Some of the advantages of an all-electronic digital readout system for microphotometry are high precision, reliability, speed, and ease of operation. Such a system is feasible if the scanning digital display can be automatically stopped at the point of minimum transmittance. One way to accomplish this is by means of a minimum-voltage memory circuit. The design and construction of such a circuit is described.
