48-964 25mm Dia. x 75mm FL VIS 0deg Coated; UV Plano-Convex Lens VIS 0° 425-675nm
The 48-964 is a 25mm diameter, 75mm focal length Plano-Convex lens, specifically designed for visible light with a 0-degree angle of incidence. Sourced from Edmund Optics, this lens is coated with a standard curve on both the front and back surfaces, ensuring optimal performance within the visible light spectrum (425-675nm).
The lens is made from fused silica (mal-1965), a material known for its excellent transparency and resistance to thermal shock. The geometry of the lens includes a 2.08mm edge thickness and a 4.43mm center thickness, providing a robust structure suitable for various applications. The lens's base shape is circular, and it features a spherical design with an inner radius of 0mm and an outer radius of 0mm.
The lens's effective focal length (EFL) is 75mm, and its back focal length (BFL) is 71.96mm. The radius of curvature (R1) is 34.39mm. These specifications make the lens ideal for applications that require a long focal length and a large diameter.
