Sapphire Lenses

Name: Sapphire Lenses
Brand: Shenzhen Solar Valley Scitech Development Co., Ltd.

Sapphire lenses are manufactured with unparalleled precision through the use of advanced multi-axis free-form surface machining technology. The production process encompasses ultra-precision fine cutting, detailed grinding, exact measurement, and meticulous polishing. Each step is meticulously managed, ensuring the machinery and the environment are precisely controlled to achieve the highest standards of optical surface machining. The application of sophisticated correction polishing technology further refines the lens surface. As a result, these sapphire lenses achieve an exceptional level of optical aspherical surface shape accuracy of ≤0.1 micron and a surface roughness of Ra≤0.01 micron, making them ideal for applications requiring the utmost in optical clarity and durability.
