84-276 50.0mm Dia. x 500.0mm FL; Plano-Convex Lens Laser V-Coat 1550nm

The 84-276 is a Plano-Convex spherical lens, a type of optical lens featuring one flat and one curved surface, designed and manufactured by Edmund Optics. This lens boasts a substantial 50.0mm diameter and a long focal length of 500.0mm, making it suitable for a wide range of applications, particularly those requiring high precision and large-scale focusing.

The lens is crafted from the high-quality material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including high transmission in the visible and near-infrared regions. This material also offers excellent homogeneity, making it an ideal choice for applications demanding high-quality imaging and precise light control.

The 84-276 features a center thickness of 5.0mm and an edge thickness of 3.79mm, providing robustness and stability to the lens. The lens's effective focal length (EFL) is 500.0mm, and the radius of curvature (R1) is 258.4mm, contributing to its superior optical performance.

The lens is coated with Edmund Optics' Laser V-Coat 1550, a highly durable and efficient coating designed for use in the 1550nm wavelength region. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving overall system efficiency.
