45-433 5.0mm Dia. x 12.0mm FL; Uncoated; Plano-Convex Lens

The 45-433 is a 5.0mm diameter, 12.0mm focal length Plano-Convex lens, sourced from the renowned optical components vendor, Edmund Optics. This lens, designed for general-purpose use, is uncoated, offering a cost-effective solution for applications that do not require specialized coatings.

The lens's geometry is characterized by a 1.25mm edge thickness and a 1.77mm center thickness, ensuring structural integrity and minimal distortion. The base shape is circular, providing a wide field of view and uniform illumination. The lens's shape is spherical, with a 6.22mm radius of curvature on the curved surface, contributing to its high optical quality.

The lens is made from N-BK7 Schott glass, a popular material due to its excellent optical properties and broad transmission range. It is designed to operate at a wavelength of 587.6nm, making it suitable for a wide range of applications, including imaging, illumination, and beam shaping.

The lens's back focal length is 10.83mm, providing a long focal length relative to its diameter, ideal for applications requiring a narrow beam or high magnification. The lens's effective focal length is 12mm, which, combined with its high-quality glass and spherical design, ensures excellent image quality and low distortion.
