89-220 6mm Dia. x 24mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
The 89-220 is a high-quality double-convex lens, boasting a 6mm diameter and a focal length of 24mm. 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, ensuring durability and reliability. It features a base shape of a circle and a spherical geometry, with an inner radius and outer radius of 0. This spherical shape is characterized by its first and second radii, R1 and R2, which measure 24.36mm and -24.36mm respectively.
The lens's thickness varies, with the edge measuring 2.23mm and the center at 2.6mm. The back focal length (BFL) is 23.13mm, and the effective focal length (EFL) is 24mm.
The 89-220 lens is coated with YAG-BBAR, a proprietary coating from Edmund Optics, designed to enhance performance within the wavelength range of 500-1100nm. This coating is applied to both the front and back surfaces of the lens, further optimizing its optical properties.
