Production and Quality Control of the CMS End Cap Hadron Calorimeter Optical Elements

The end cap hadron calorimeter designed for the Compact Muon Solenoid (CMS) experiment is a sampling calorimeter with active elements based on scintillators read by wave length shifting fibers. We have fabricated 1368 optical elements containing 21096 scintillators. The production and the quality control of the optical elements are described.
