89-233 10mm Dia. x 20mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
The 89-233 is a high-quality double-convex lens, boasting a 10mm diameter and a focal length of 20mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock, ready for immediate use.
The lens is constructed from the premium material, n-BK7 Schott, which is known for its excellent optical properties and durability. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 20.24mm and -20.24mm, respectively. This geometry results in a back focal length of 19.16mm and an effective focal length of 20mm.
The lens is coated with a high-performance YAG-BBAR coating, which is designed to operate within the wavelength range of 500-1100nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving overall image quality. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
