Sapphire underwater camera lens protective glass

Underwater cameras generally require deep water operation, and the protective glass of the camera lens needs to withstand high-intensity water pressure to avoid being crushed; Scratches and other debris can cause cracks, resulting in unclear camera imaging; Additionally, the camera generates a certain amount of heat after operation, resulting in an increase in operating temperature.

Sapphire glass has high hardness (Mohs India 9), high transmittance (after polishing and coating, the transmittance can reach over 95%), wear resistance and scratch resistance, making it very suitable for underwater cameras working in extremely deep water environments. Like underwater cameras, sapphire material itself has the characteristic of acid and alkali resistance, which can adapt to underwater environments with high salinity.
