45-151 50.0mm Dia. x 200.0mm FL; Plano-Convex Lens Uncoated

The 45-151 is a Plano-Convex lens with a diameter of 50.0mm and a focal length of 200.0mm, sourced from the reputable optical vendor, Edmund Optics. This lens is uncoated, offering a high-quality, cost-effective solution for various optical applications.

The lens's geometry is characterized by a convex surface with a radius of curvature of 103.36mm, resulting in a back focal length of 196.66mm. The edge thickness measures 2mm, while the center thickness is 5.07mm, providing a robust and durable structure. The lens's design is circular, ensuring a wide field of view and minimal distortion.

The lens is made of N-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties and versatility. It is specifically designed for a central wavelength of 587.6nm, making it suitable for applications in the visible spectrum.

The uncoated surface of the lens provides a bare, unrefined optical finish. While coatings can enhance performance by reducing reflection and increasing transmission, this uncoated lens offers a more affordable option, making it an ideal choice for budget-conscious projects or where coating is not critical.
