48-264 50mm Dia. x 250mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 48-264 is a Double-Convex Lens, a type of Spherical Lens, sourced from Edmund Optics. This lens boasts a 50mm diameter and a focal length of 250mm, designed for the visible light spectrum with a 0-degree angle of incidence. The lens is made from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties.
The 48-264 features a standard coating on both the front and back surfaces, specifically the EDM VIS-0 STD CURVE coating. This coating is designed to optimize performance within the visible light spectrum, specifically between 425-675nm. The lens has a central thickness of 4.93mm and an edge thickness of 2.5mm, providing a robust and durable structure.
The lens's geometry is meticulously designed with an inner radius of 0mm and an outer radius of 0mm. The front and back radii are 257.57mm and -257.57mm, respectively, contributing to its double-convex shape. The back focal length (BFL) is 248.37mm, and the effective focal length (EFL) is 250mm, demonstrating the lens's high-quality optical performance.
