SLB-25.4-100N 25.4 mm Dia. x -100.0 mm FL; Plano-Concave Lens Uncoated
OptoSigma offers the SLB-25.4-100N, a Plano-Concave Lens with a 25.4 mm diameter and a focal length of -100.0 mm. This lens is uncoated and features a spherical shape, designed for use in various optical applications.
The lens is made from n-BK7 Schott material, a popular choice for its high refractive index and low dispersion properties. The geometry of the lens includes a thickness edge of 3.6 mm and a thickness center of 2 mm, providing a robust structure suitable for various environments.
The lens's base shape is circular, and it has an inner radius of 0 mm and an outer radius of 0 mm. The effective focal length (EFL) is -100.0 mm, and the radius of curvature (R1) is -51.9 mm. The back focal length (BFL) is -101.3 mm.
The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, uncoated lenses can be more cost-effective and are often sufficient for many applications.
