45-083 12.0mm Dia. x 12.0mm FL; Uncoated; Plano-Convex Lens

The 45-083 is a 12.0mm diameter by 12.0mm focal length Plano-Convex lens, sourced from the renowned optical components vendor, Edmund Optics. This uncoated lens is a spherical element, boasting a base shape of a circle, and is designed for use in a wide range of optical applications.

The lens's geometry is meticulously crafted, with a thickness at the edge of 1.84mm and a center thickness of 4mm. It offers an effective focal length (EFL) of 12mm, making it a versatile choice for various optical systems. The curvature of the lens is defined by a radius of 9.42mm for the first surface, and a back focal length (BFL) of 9.76mm. The lens does not have any inner or outer radius, indicating a uniform curvature throughout.

The lens is made from n-SF11 Schott, a high-index glass with excellent optical properties. It is designed to operate at a wavelength of 587.6nm, which falls within the visible light spectrum. The lens's shape is spherical, a common choice for its ease of manufacturing and versatility in optical systems.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. This may result in higher reflectivity at the air-glass interfaces, which could impact the performance in certain applications. However, uncoated lenses can be advantageous in specific scenarios, such as when cost, ease of cleaning, or simple system design are priorities.
