89-268 25mm Dia. x 50mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
This is a 25mm diameter, double-convex lens with a focal length of 50mm, sourced from the renowned optical component vendor, Edmund Optics. The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties and durability.
The lens features a YAG-BBAR coating on both the front and back surfaces, which is designed to enhance its performance within the wavelength range of 500-1100nm. This coating reduces reflection and increases transmission, making the lens ideal for use in a wide range of applications, including imaging systems, beam shaping, and laser applications.
The geometry of the lens includes an edge thickness of 1.88mm and a center thickness of 5mm. The front and back radii of curvature are 50.8mm and -50.8mm respectively, resulting in a back focal length of 48.29mm. The lens has no inner or outer radius, indicating a uniform thickness across the lens.
