89-273 25mm Dia. x 175mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
The 89-273 is a high-quality double-convex lens, sourced from the renowned optical component vendor, Edmund Optics. This lens boasts a 25mm diameter and a focal length of 175mm, making it suitable for a wide range of optical applications.
The lens is constructed from Schott's n-BK7 glass, a popular material due to 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 180.4mm and -180.4mm for the first and second surfaces, respectively. This geometry results in a back focal length of 173.94mm.
The lens is coated with YAG-BBAR, a broadband anti-reflection coating that is effective in the 500-1100nm wavelength range. This coating is applied to both the front and back surfaces of the lens, reducing surface reflections and enhancing transmission. The coating also provides excellent environmental stability and resistance to wear, ensuring the longevity and performance of the lens.
The lens has a thickness of 2.33mm at the edge and 3.2mm at the center. The inner and outer radii are 0mm, indicating a uniform curvature across the lens surface. The lens is in stock and available for immediate shipping, as indicated by the valid weblink status.
