69-403 25.0mm Dia. x 300.0mm FL; Plano-Convex Lens Laser V-Coat 532nm

The 69-403 is a Plano-Convex spherical lens, a type of optical component characterized by its single curved surface and a flat surface on opposite sides. This lens, sourced from Edmund Optics, boasts a diameter of 25.0mm and a focal length of 300.0mm, making it suitable for a wide range of applications.

The lens is crafted from the material n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material is particularly suitable for use in the visible and near-infrared spectrum, making the 69-403 an ideal choice for applications involving wavelengths of 532nm.

The lens features a front and back coating of EDM Las V-Coat 532, a specialized coating designed to enhance the lens's performance in laser applications. This coating reduces reflection and increases transmission, thereby improving the efficiency and effectiveness of the lens in laser systems.

The geometry of the lens includes a thickness of 2.5mm at the edge and 3.0mm at the center, with an effective focal length (EFL) of 300.0mm. The lens's inner and outer radii are both 0, indicating a symmetrical design. The radius of curvature (R1) is 155.04mm, contributing to the lens's focusing power.
