45-085 12.0mm Dia. x 30.0mm FL; Uncoated; Plano-Convex Lens

The 45-085 is a Plano-Convex lens with a 12.0mm diameter and a 30.0mm focal length, sourced from the renowned optical component vendor, Edmund Optics. This lens, designed for general-purpose use, is uncoated, offering a simple yet effective solution for various optical applications.

The lens's geometry is characterized by a 1.79mm edge thickness and a 3.0mm center thickness, providing a balance between weight and optical performance. The base shape is circular, ensuring consistent light distribution and minimal distortion. The effective focal length (EFL) is 30.0mm, making it suitable for applications requiring moderate magnification and a wide field of view.

The lens is made of N-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties and versatility. The material's Abbe number is 64.17, and its refractive index at the specified wavelength (587.6nm) is 1.5168. This combination ensures high image quality, low dispersion, and high transmission across the visible spectrum.

The Plano-Convex lens's surface has a radius of curvature of 15.5mm, contributing to its compact design and efficient light-gathering capabilities. The back focal length (BFL) is 28.02mm, allowing for sufficient space between the lens and the image sensor or other optical components.
