Sapphire Protective Lens is an optical lens, typically made from single crystal sapphire and features extremely high surface hardness, high thermal conductivity, high dielectric constant, and resistance to common chemical acids and bases, designed to protect other optical components and systems from damage, especially during laser applications like cutting, welding, and engraving. It acts as a barrier against debris, splatter, and the direct impact of the laser beam, preventing damage to more sensitive elements within the optical path.
Mohs hardness 9, resistant to scratches and abrasion from most sharp and hard objects; no surface damage after long-term use, avoiding frequent replacement of optical components.

Wide working temperature range: -200℃ ~ 1900℃, no deformation, no cracking and no performance attenuation in high-temperature laser processing, high-temperature smelting and other extreme environments.

CNC precision grinding and polishing, strict dimensional tolerance control, excellent surface flatness; seamless fit with equipment, no light refraction distortion, ensuring the stability of optical path.
