47-489 9mm Dia. x 36mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 47-489 is a high-quality spherical lens, boasting a 9mm diameter and a focal length of 36mm, making it a versatile choice for various optical applications. This lens is sourced from the reputable vendor, Edmund Optics, ensuring reliability and performance.
The lens is designed with a double-convex geometry, featuring two convex surfaces (r1: 36.77, r2: -36.77) that effectively focus light. The lens's thickness at the edge is 2mm, while the center thickness is 2.55mm, providing a balanced structure for efficient light transmission. The effective focal length (EFL) is 36mm, and the back focal length (BFL) is 35.15mm, offering a wide range of optical possibilities.
The lens is crafted from the renowned material, n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties. This material ensures high light transmission and low dispersion, making it ideal for various applications within the visible spectrum (425-675nm).
The lens features a standard VIS 0° coating on both the front and back surfaces, enhancing its performance in the visible light range. This coating reduces surface reflections, improving light transmission and overall image quality.
