LDX-25.0-18.5-C 25 mm Dia. N-BK7 Image Grade Convex-Convex Lens; EFL=20mm Uncoated
This is the LDX-25.0-18.5-C, a high-quality convex-convex lens from CVI Laser Optics. The lens, which is 25 mm in diameter, is made from N-BK7 Schott glass, a popular material for its excellent optical properties and high damage threshold.
The lens features a double-convex design with radii of curvature of 18.5 mm and -18.5 mm, respectively. This design results in an effective focal length (EFL) of 20 mm, making it suitable for a wide range of optical applications that require a compact, high-performance lens.
The lens has a center thickness of 11.8 mm and an edge thickness of 2.1 mm, providing excellent mechanical stability and resistance to optical distortions. The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it can be beneficial in certain applications where coatings may introduce unwanted spectral characteristics.
The LDX-25.0-18.5-C is part of CVI Laser Optics' spherical lens catalog, which includes a wide range of lenses with various shapes, sizes, and materials. The lens is in stock and available for immediate shipping, as indicated by its valid weblink status.
