89-234 10mm Dia. x 25mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
The 89-234 is a high-quality double-convex lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a 10mm diameter and a focal length of 25mm, making it suitable for a wide range of optical applications.
The lens is crafted from the high-grade material, n-BK7 Schott, which is known for its excellent optical properties. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 25.41mm and -25.41mm, respectively. This geometry results in a back focal length of 24.16mm and an effective focal length of 25mm.
The lens is coated with a premium YAG-BBAR coating, which is designed to enhance its performance within the wavelength range of 500-1100nm. This coating is applied to both the front and back surfaces of the lens, ensuring optimal light transmission and reducing unwanted reflections.
The lens has a thickness of 1.51mm at the edge and 2.5mm at the center, providing a robust and durable structure. The inner and outer radii are 0mm, indicating a uniform curvature throughout the lens.
