89-283 40mm Dia. x 60mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
The 89-283 is a high-quality double-convex lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a diameter of 40mm and a focal length of 60mm, making it suitable for a wide range of optical applications.
The lens is crafted from Schott's n-BK7 glass, a popular material known for its excellent optical properties and versatility. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 60.56mm for the first surface and -60.56mm for the second surface. This geometry results in a back focal length of 57.1mm.
The lens is coated with YAG-BBAR, a broadband anti-reflection coating that enhances its performance in the spectral range of 500-1100nm. This coating reduces surface reflections, thereby improving transmission and minimizing losses. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
The lens has a central thickness of 8.8mm and an edge thickness of 2mm, providing robustness and durability. The lens is available for purchase through the Edmund Optics website, where it is listed as being in stock, indicating quick and convenient access for users.
