Revolutionizing Drone Protection: Meller Optics’ Sapphire Windows

Meller Optics, a leader in crafting high-precision optical components, has unveiled an innovative series of sapphire windows tailored for unmanned aerial vehicles (UAVs), remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs), and robotic systems. these advanced windows are specifically designed to safeguard the delicate optical instruments found in drones.

Engineered for Extreme Conditions

These sapphire windows are meticulously designed to endure the challenging environments that drones frequently encounter. They provide robust protection for cameras, sensors, and detectors against fast-moving particles, corrosive substances, and severe temperature fluctuations.

Unmatched Durability and Clarity

Meller’s sapphire windows are celebrated for their remarkable strength and optical transparency. With a Mohs hardness rating of 9—just below diamond—these windows deliver extraordinary resistance to scratches, dirt, and chemical damage during aerial operations. The material’s optical capabilities are equally extraordinary, allowing for light transmission of up to 85% across UV to IR wavelengths when uncoated, and surpassing 99% with anti-reflective treatments.

Key Features of Meller Sapphire Windows

• Exceptional Hardness & Durability: With a Mohs hardness of 9, these windows resist damage from fast-moving debris and harsh chemicals, and also high temperatures and mechanical stress.
• Superior Optical Performance: uncoated windows transmit 85% of light (UV to IR), while those with anti-reflective coatings achieve over 99% transmission.
• Precision Surface Finishes: Available with scratch-dig ratings from 60-40 to 40-20, maintaining flatness to 0.5 fringes of HeNe.
• Dimensional Precision: Parallelism is maintained within 20 to 2 arc-seconds, ensuring optimal optical alignment.
• Versatile Size & Thickness: Offered in diameters ranging from 1/4″ to 10″ and thicknesses from 1/2 mm to 1″, accommodating various drone specifications.

Resilience in Harsh Environments

Beyond its mechanical and optical advantages, sapphire is capable of withstanding extreme environmental challenges. It can tolerate temperatures reaching up to 1,000°C and pressures as high as 10,000 psi, depending on the specific design. This unique combination of durability, clarity, and resilience positions meller Sapphire Windows as the ideal choice for protecting essential drone sensors in the most demanding operational scenarios.
