title: Optical absorption using a system reponse corrector.
abstract: We have constructed an apparatus suited for low-temperature crystal absorption measurements. The system corrects for the different optical response of the components. We have operated it between 3000 A and 24 000 A, throughout which region the error in the optical density was less than +/-0.01.
