title: Apparatus for wideband monitoring of optical coatings and its uses.
abstract: A computer controlled rapid-scanning monochromator has been constructed for monitoring optical coatings in situ, determining the optical constants of films, and measuring the optical instability of filters. In this paper are given the main specifications of the apparatus, some results in the production of a number of broadband AR coatings, and characterization of some passband filters.
