This item is a 10mm diameter, double-convex lens with a focal length of 25mm, sourced from Edmund Optics. The lens is made of the high-quality material n-BK7 Schott, which is known for its excellent optical properties. The lens features a front and back coating of edm visnir0sp2002000, providing superior Visible to Near-Infrared (VIS-NIR) transmission capabilities, enhancing its performance in a wide range of applications.
The lens has a center thickness of 2.5mm and an edge thickness of 1.51mm, providing a robust structure while maintaining a compact design. The inner and outer radii are 0mm, indicating a uniform curvature throughout the lens. The back focal length (BFL) is 24.16mm, which is a critical factor in determining the lens's performance in various optical systems.
The lens's geometry and material make it suitable for use in a wide range of applications, including but not limited to, imaging systems, beam shaping, and laser applications. The VIS-NIR coating enhances its performance in applications where infrared transmission is required, such as thermal imaging and night vision systems.
