89-260 20mm Dia. x 40mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm

This is a high-quality double-convex lens from the renowned optical components manufacturer, Edmund Optics. The lens, identified as the 89-260, boasts a 20mm diameter and a focal length of 40mm, making it suitable for a wide range of applications.

The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties and durability. The front and back surfaces of the lens are coated with YAG-BBAR, a type of coating that enhances the lens's performance in the 500-1100nm wavelength range. This makes the lens ideal for use in applications such as laser systems, imaging systems, and other optical systems that require high-performance lenses.

The lens has a center thickness of 5.3mm and an edge thickness of 2.8mm, providing a good balance between weight and durability. The inner and outer radii of the lens are 0mm, indicating a uniform curvature across the lens surface. The back focal length of the lens is 38.44mm, which should be taken into account when designing the optical system.

The lens is available from Edmund Optics and is currently in stock, making it a readily available option for your optical system needs. The detailed specifications and the availability of the lens are provided on the Edmund Optics website, along with other relevant information.
