    Sapphire Lenses

    • Introduction

    Sapphire Lenses


    Sapphire is the best medium for spherical lenses that require a broad spectrum of light transmission and high optical clarity, especially in demanding applications such as laser system or working under harsh environmental conditions. With its excellent hardness, high thermal conductivity and resistance to chemical acids and alkalis, sapphire’s physical property is hard to machine, also requires unique polishing techniques.
