43-820 2.50 mm Dia. Ruby Doped Sapphire Ball Lenses Uncoated

The 43-820 is a 2.50 mm diameter ball lens, characterized by its ruby doped sapphire material, and uncoated surface. This lens, sourced from Edmund Optics, is a versatile component in the realm of optical systems, offering unique properties that make it suitable for various applications.

The lens's base shape is circular, with a diameter of 2.50 mm, making it compact and ideal for use in confined spaces. The geometry of the lens is defined by its inner radius, which is zero, and its outer radius, also zero, indicating a uniform curvature throughout.

The material of the lens is ruby doped sapphire, identified by the Material ID "al2o3 mal-1972-n-o". This material is known for its excellent optical properties, including high transparency and durability. The ruby doping provides additional benefits, such as enhanced thermal conductivity and resistance to chemical attack.

The wavelength of the lens is 587.6 nm, suggesting its suitability for applications that operate within this wavelength range. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this does not necessarily diminish its performance, especially in applications where coating is not a critical factor.
