89-227 9mm Dia. x 36mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
The 89-227 is a high-quality double-convex lens, boasting a 9mm diameter and a focal length of 36mm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is constructed 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 geometry that includes a 2mm thickness at the edge and a 2.55mm thickness at the center. The effective focal length (EFL) is 36mm, and the radii of curvature are 36.77mm for the first surface and -36.77mm for the second surface. The back focal length (BFL) is 35.15mm.
The 89-227 lens is coated with YAG-BBAR, a highly durable and efficient coating that operates within the wavelength range of 500-1100nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
