When selecting optical-grade sapphire plates, it is essential to consider the following five criteria to ensure optimal performance and cost-effectiveness of the product. These criteria include material purity, surface accuracy, transmittance, processing capacity and coating process. Focusing on these key parameters is crucial to avoid compromising core specifications in the pursuit of low prices.

Sapphire glass is a superior material for use in lenses when compared with traditional mineral glass or resin lenses. The key benefit of sapphire glass is that it maintains consistent performance over a long period of time. For instance, in the friction test simulating daily use, the number of surface scratches on the glass...

Many optical engineers are often confused when they first come into contact with sapphire plates. Despite being optical windows, sapphire is more expensive and more difficult to process than ordinary glass. What are the reasons for this? This article commences with a review of prevalent cognitive misconceptions and provides comprehensive responses to critical technical inquiries...

Sapphire is a hard oxide crystal that boasts excellent optical, physical and chemical properties. Its Mohs hardness is as high as 9, second only to diamond, and it has excellent chemical stability, with no absorption peaks in the 0.3-5.5μm spectral range. Consequently, it is suitable for use as a new type of substrate and...

Sapphire is composed of single-crystal aluminium oxide, a compound known for its remarkably strong interatomic binding forces. At room temperature, most chemical substances are incompatible with sapphire. This includes concentrated sulfuric acid, concentrated nitric acid, aqua regia, sodium hydroxide, ammonia water and various organic solvents.
