Optimax has developed a novel optical coating (OTR-AR) that protects optical surfaces in even the most extreme environmental use conditions. OTR coatings have been demonstrated to provide excellent resistance to latent scratching, staining and dimming of chemically sensitive optical glass surfaces in hot- humid environments.

1. INTRODUCTION

The transmitted performance of chemically sensitive glasses can degrade over time when exposed to high humidity for prolonged periods of time. A worst-case scenario for these glasses is prolonged exposure to liquid water via condensation, contact with wet packaging, and/or improper cleaning. To provide protection of chemically sensitive glass surfaces under extreme environmental conditions Optimax has developed a novel optical coating (OTR- AR)....
