48-263 50mm Dia. x 200mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 48-263 is a high-quality Double-Convex Lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a 50mm diameter and a focal length of 200mm, making it suitable for a wide range of applications.
The lens is crafted from the esteemed N-BK7 Schott material, a borosilicate crown glass known for its excellent optical properties. This material ensures high transmission and low dispersion, making it an ideal choice for various optical systems.
The 48-263 features a standard coating on both the front and back surfaces, specifically the EDM VIS-0 STD CURVE coating. This coating enhances the lens's performance in the visible light spectrum, particularly between 425-675nm. It reduces surface reflections, thereby increasing transmission and improving overall image quality.
The lens's geometry is another notable feature. It has an edge thickness of 2mm and a center thickness of 5.05mm. The first radius of curvature (R1) is 205.86mm, while the second radius (R2) is -205.86mm. The back focal length (BFL) is 198.33mm, and both the inner and outer radii are 0mm.
