49-184 3mm Dia. x 9mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 49-184 is a high-quality Double-Convex Lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 3mm and a focal length of 9mm, is designed for use within the visible light spectrum, specifically between 425-675nm.
The lens is constructed 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 color correction.
The 49-184 features a standard anti-reflection coating on both the front and back surfaces. This coating, identified as 'edm vis-0 std curve', is designed to minimize surface reflections and increase transmission within the visible light spectrum. The coating also helps to reduce ghosting and flaring, further enhancing the lens's performance.
The lens's geometry is characterized by its edge thickness of 1.35mm and center thickness of 1.6mm. The front and back radii of curvature are 9.02mm and -9.02mm, respectively, resulting in a back focal length of 8.46mm. The lens's shape is spherical, ensuring a wide field of view and minimal distortion.
