49-182 3mm Dia. x 4.5mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 49-182 is a high-quality Double-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens, with a diameter of 3mm and a focal length of 4.5mm, is designed for use within the visible light spectrum, specifically between 425-675nm.
The lens is crafted from Schott's n-BK7 glass, a material well-known for its excellent optical properties, including a high Abbe number and low dispersion. This makes the lens ideal for applications that require high image quality and minimal chromatic aberration.
The 49-182 features a standard EDmund Vis-0 coating on both the front and back surfaces. This coating is designed to enhance the lens's performance within the visible light spectrum, improving transmission and reducing surface reflections. The coating also provides a degree of protection against environmental factors, such as dust and moisture.
The lens's geometry is meticulously designed, with an edge thickness of 1.47mm and a center thickness of 2mm. The front and back radii of curvature are 4.29mm and -4.29mm, respectively, contributing to the lens's double-convex shape. The back focal length is 3.78mm, and the lens has no inner or outer radius, indicating a uniform thickness.
