Calcium Fluoride > Window CaF2

Introduction

Used as transparent barriers for sending and receiving light between two phases under varying conditions in temperature pressure chemical composition cleanliness and phase. Windows of synthetic optical CaF2 are highly abrasion-resistant with hardness approaching that of diamonds. The material allows transmission of light in the range from ultraviolet to near-infrared.
