49-557 0.50 mm Dia. Ruby Doped Sapphire Half-Ball Lenses Uncoated

The 49-557 is a 0.50 mm diameter Ruby Doped Sapphire Half-Ball Lens, uncoated, sourced from the renowned optical components vendor, Edmund Optics. This half-ball lens, with its base shape being circular, is a unique optical element designed for specific applications.

The lens has a diameter of 0.50 mm, making it suitable for use in compact optical systems. The thickness of the lens is 0.25 mm, providing a balance between optical performance and mechanical robustness. The inner radius of the lens is 0, indicating a flat surface on one side, while the outer radius is also 0, suggesting a curved surface on the other side.

The material of the lens is Ruby Doped Sapphire, specifically identified as al2o3 mal-1972-n-o in the material database. This material is known for its excellent optical properties, including high transparency and robustness, making it ideal for use in various optical applications.

The lens is designed to operate at a wavelength of 587.6 nm, which is within the visible light spectrum. This makes it suitable for applications that involve visible light, such as imaging or illumination systems.

Notably, the lens is uncoated. While coatings can enhance the optical performance of a lens by reducing reflections or increasing transmission, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
