48-769 25.0mm Dia. x 40.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm

The 48-769 is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens boasts a diameter of 25.0mm and a focal length of 40.0mm, 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 high transparency and low auto-fluorescence. This material is particularly suitable for use in the near-infrared (NIR) region, specifically between 600-1050nm, as indicated by the item's name.

The 48-769 features a standard coating on both the front and back surfaces, specifically the EDM NIR-I std curve coating. This coating enhances the lens's performance in the NIR region, providing improved transmission and reduced reflection.

In terms of geometry, the lens has an edge thickness of 1.39mm and a center thickness of 5.6mm. The inner and outer radii are both zero, indicating a plano-convex shape. The lens's effective focal length (EFL) is 40mm, and the back focal length (BFL) is 36.31mm. The radius of curvature (R1) is 20.67mm.
