SLB-30-400P 30.0 mm Dia. x 400.0 mm FL; Plano-Convex Lens Uncoated

The SLB-30-400P is a Plano-Convex lens, part of OptoSigma's extensive catalog of optical elements. This lens, with a diameter of 30.0 mm and a focal length of 400.0 mm, is designed for use in a wide range of optical applications.

The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high chemical durability. The Plano-Convex geometry, where one side is flat and the other is curved, is a common shape in optical lenses. This particular lens has an inner radius of 0 mm and an outer radius of 0 mm, indicating a symmetrical curvature.

The lens has a thickness of 2 mm at the edge and 2.5 mm at the center. The effective focal length (EFL) is 400.0 mm, and the back focal length (BFL) is 398.2 mm. The radius of curvature (R1) is 207.6 mm. The wavelength for this lens is 546.1 nm.

Notably, this lens is uncoated. Coatings are often applied to lenses to reduce reflection, increase transmission, or provide other desirable optical properties. However, this lens, in its uncoated form, offers a more basic optical performance.
