Abstract : A functioning optical component absorption measurement facility has been assembled to (1) develop technical competency in evaluating the effectiveness of the technique, and (2) implement the technique as a routine measurement procedure for optical component evaluation. Both objectives have been partially successful. The conclusions of this research are that (1) measurement accuracy is highly dependent on component selection and assembly; (2) many variables must be considered when using the technique; and (3) the technique has the capability to measure one of the many variables involved in photoacoustic absorption. The research and measurements are being transitioned into mission and support project work.
