Abstract This work deals with the optical characterization of the surface of EG&G and Hamamatsu APD's and performance of an antireflection coating made of Y2O3 and deposited on a PWO test piece. The effectiveness of antireflection treatments of PWO and Si surfaces is evaluated in a simplified and a realistic situation by means of the ratio of "detected to emitted photons". The complex refractive index of the Dow Corning 02-3067 optical grease is also reported.
