Research output: Contribution to journalArticlepeer-review

Abstract

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.
