Square sapphire optical glass for Protective window by Customzied size ＆sapphire window lens ＆Sapphire optical Windows Manufacturers.
Optical windows are applied for protecting fragile optical components inside an equipment or directly used for watching windows because of its very good physical property.
For the physical characteristics of sapphire glass have a high temperature resistance of 2000 degrees and 9.0 hardness ,85%transmittance；
it is gradually replacing the transparent glass such as quartz glass and Corning glass because of the trend of lower and lower materials price.
they are adopted to isolate two physical environments while allowing light to pass. Optical Sapphire windows refer to a piece of transparent optical material that allows light into an optical instrument. They are pieces of optical glasses with ground and polished faces that are relatively parallel.
Sapphire optical windows are high-performance components used in various optical applications, offering exceptional durability and optical clarity. These windows are made from sapphire, a material renowned for its remarkable physical properties, including a high temperature resistance of up to 2000 degrees Celsius and a hardness of 9.0 on the Mohs scale. With 85% light transmittance, sapphire optical windows allow light to pass through with minimal distortion, making them ideal for protecting sensitive optical equipment while maintaining optical performance.
Due to its superior characteristics, sapphire optical windows are increasingly replacing traditional materials like quartz and Corning glass, driven by advances in manufacturing technology and a reduction in material costs. They serve not only as protective barriers for optical instruments but also function as transparent interfaces that isolate two distinct physical environments while permitting the transmission of light.
These sapphire windows are precision-engineered with ground and polished surfaces to ensure parallelism and optical clarity, making them crucial in industries such as aerospace, telecommunications, and high-end optical devices. As a result, sapphire optical windows are becoming the preferred choice for a wide range of applications, offering both reliability and cost-effectiveness in modern optical systems.
