Revolutionizing Drone Vision: Meller Sapphire Optics

Meller Optics offers high-performance sapphire lenses, windows, and domes specifically engineered to safeguard drone vision systems in extreme environments.

Unmatched durability for UAV Applications

designed for both commercial and military unmanned aerial vehicles (UAVs), these optics exhibit remarkable resistance to various environmental challenges, including abrasive materials, elevated temperatures, and chemical exposure.

The Strength of Sapphire

Sapphire, with a hardness rating of Mohs 9—just below diamond—provides remarkable protection against scratches and abrasions. This durability is crucial for withstanding fast-moving particles like dirt, sand, and saltwater, as well as harsh chemicals. Such resilience guarantees the longevity and reliability of essential imaging and sensing technologies.Furthermore, sapphire’s extensive transmission spectrum, spanning from ultraviolet (UV) to infrared (IR), makes it suitable for a wide range of optical applications. Optional multi-spectral anti-reflective coatings can boost transmission rates to over 99%, significantly enhancing overall performance.

Customizable Solutions for Specific Needs

Meller’s sapphire optics can be tailored to meet unique specifications. Windows are offered in three quality tiers—Standard, Superior, and High-Precision—with customizable options for diameter, thickness, and orientation. Domes can be produced with diameters reaching up to 100mm and viewing angles of up to 180 degrees, featuring wall thickness variations of less than 25 microns and dimensional tolerances as precise as ±10 microns. Lenses, available in both positive and negative configurations, can be customized for diameter and focal length, with options for anti-reflection and other thin-film coatings.

Advanced Manufacturing capabilities

Meller Optics boasts thorough in-house manufacturing capabilities, including 5-axis CNC machining, surface grinding, and both single and double-side polishing. The company employs X-ray crystal analysis, interferometric measurement, and surface roughness analysis to ensure precision. Meller is ISO 9001:2015 certified and adheres to ITAR and DFARS regulations, guaranteeing adherence to high production standards.
