Abstract
(Abstract only) Some of the Schott glasses originally prescribed by Bessell in creating Johnson/Cousins UBVRcIc photometric filters for use in CCD cameras are no longer available. We have selected new glasses, and added interference coatings, to create a new set of filters that accurately match the original Johnson/Cousins bandpasses. This paper will describe the new prescriptions and give preliminary results from on-telescope tests.
