SLB-07-20P 7.0 mm Dia. x 20.0 mm FL; Plano-Convex Lens Uncoated
The SLB-07-20P is a 7.0 mm diameter, plano-convex lens with a focal length of 20.0 mm, sourced from the reputable optical components vendor, OptoSigma. This lens is made of the high-quality material, n-BK7 Schott, which is renowned for its excellent optical properties, making it suitable for a wide range of applications.
The lens geometry features a convex surface with a radius of curvature of 10.38 mm, and a thickness of 1.7 mm at the edge, increasing to 2.3 mm at the center. The lens has a clear aperture, with no inner or outer radius specified, indicating a uniform, circular profile. The effective focal length (EFL) of the lens is 20.0 mm, and the back focal length (BFL) is 18.5 mm.
Notably, this lens is uncoated, which means it does not have any anti-reflective or other surface coatings. While this may result in higher reflective losses, it also means the lens can be used in a broader spectral range without the risk of coating damage or spectral shifts.
