89-277 30mm Dia. x 50mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
The 89-277 is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens boasts a 30mm diameter and a focal length of 50mm, making it suitable for a wide range of optical applications.
The lens is constructed from Schott's n-BK7 glass, a popular material in the optical industry 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 50.56mm on both surfaces. This geometry contributes to the lens's high optical power and excellent imaging capabilities.
The 89-277 is coated with YAG-BBAR on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet Broadband Anti-Reflection, is designed to minimize reflection and maximize transmission across the 500-1100nm wavelength range. This makes the lens ideal for use in applications such as laser systems, spectroscopy, and imaging systems that operate within this wavelength range.
The lens has a thickness of 2mm at the edge and 6.55mm at the center. The inner and outer radii are 0mm, indicating a uniform curvature across the lens surface. The effective focal length (EFL) of the lens is 50mm, and the back focal length (BFL) is 47.82mm.
