48-245 50.0mm Dia. x 75.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm

This product is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 48-245, boasts a diameter of 50.0mm and a focal length of 75.0mm, making it a versatile choice for various optical applications.

The lens is crafted from the high-quality material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material is widely used in the optical industry for its superior performance.

The lens features a standard coating on both the front and back surfaces. The coating, referred to as 'edm vis-0 std curve', is designed to optimize performance within the visible light spectrum, specifically between 425-675nm. This coating enhances the lens's light transmission capabilities and reduces surface reflections, thereby improving overall system performance.

The geometry of the lens is also noteworthy. It has an edge thickness of 1.86mm and a center thickness of 11mm. The radius of curvature (R1) is 38.76mm, and the back focal length (BFL) is 67.75mm. The lens's base shape is circular, and its shape is spherical, which is common in optical systems due to its ease of manufacturing and high optical quality.
