Compensation for Thermal Drift in an Optical Feedback Stabilized Photometer

David R. Senn, Peter W. Carr

Research output: Contribution to journalArticlepeer-review


A simple circuit based upon an equal arm Wheatstone Bridge which senses temperature changes of the optical chassis permits compensation of thermally induced long term drift in a single beam optical feedback stabilized photometer. A drift rate of 0,004% T/hr was achieved.
