Product Description

General Introduction: Raytek's uncoated sapphire window stands as an epitome of resilience, excelling in the most challenging conditions such as high temperatures, immense pressure, vacuum extremes, or corrosive environments. This exceptional material, sapphire, boasts unparalleled compressive strength and extraordinary acid resistance.
Unique characteristics of sapphire materials
Sapphire, as a single crystal form of alumina, distinguishes itself with superior chemical, mechanical, and optical properties. Renowned for its exceptional resistance to strong acids, sapphire thrives in corrosive environments. Its surface, remarkably scratch and wear-resistant, achieves a Knoop hardness of 1800 when aligned parallel to the optical axis (c-axis) and an impressive 2200 perpendicular to it.
