SLB-25-60N 25.0 mm Dia. x -60.0 mm FL; Plano-Concave Lens Uncoated

The SLB-25-60N is a Plano-Concave Lens, a type of spherical lens, sourced from OptoSigma. This lens has a base shape of a circle and is uncoated. The lens is designed with a diameter of 25.0 mm and a thickness at the edge of 4.6 mm, while the center thickness is 2.0 mm. The effective focal length (EFL) of this lens is -60.0 mm, making it a negative or diverging lens.

The lens's first radius of curvature (R1) is -31.14 mm, and the back focal length (BFL) is -61.3 mm. The lens does not have an inner or outer radius, indicating that it is a simple plano-concave lens without any additional curvature on the edges.

The lens is made of n-BK7 Schott, a common and versatile optical glass. The wavelength for this lens is 546.1 nm. This lens is in stock and available for immediate purchase, as indicated by its web link status.
