## Abstract

Proposed as part of the next generation of water Cherenkov detectors, Hyper-Kamiokande will have a vastly improved potential in determining leptonic CP violation in neutrino oscillations. Well understood optical diffusers are needed as part of an integrated light injection system for calibration of ultrasenstive photo-detectors. Research and development into optical diffuser technology is presented and summaries of recent installations in Super-Kamiokande are discussed.
