89-265 25mm Dia. x 30mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
The 89-265 is a high-quality double-convex lens, designed and manufactured by Edmund Optics. This lens boasts a 25mm diameter and a focal length of 30mm, making it suitable for a wide range of optical applications.
The lens is constructed from n-SF5 Schott, a material 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 39.22mm and -39.22mm respectively. This geometry results in a back focal length of 28.31mm and an effective focal length of 30mm.
The lens is coated with YAG-BBAR on both the front and back surfaces, providing superior transmission in the 500-1100nm wavelength range. This coating enhances the lens's performance in various applications, including but not limited to, imaging, beam shaping, and laser systems.
The lens has a thickness of 1.41mm at the edge and 5.5mm at the center, providing robustness and durability. The lens is currently in stock and available for immediate shipping, as indicated by its weblink status.
