The key distinction between sapphire glass and ordinary transparent glass is in their composition. Sapphire is not a natural gemstone, but a synthetic single-crystal aluminium oxide with a Mohs hardness of 9, second only to diamond. However, the hardness of ordinary glass typically ranges from 5 to 6 on the Mohs scale. This means that sapphire...

High-hardness sapphire glass is a popular choice in certain industrial processes due to its physical properties and optical performance. This type of material generally requires precise processing and customized services to meet the requirements of different equipment for dimensional tolerances, surface finish and heat resistance. For users, the focus is frequently on the consistency...

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...
