SLB-25.4-50N 25.4 mm Dia. x -50.0 mm FL; Plano-Concave Lens Uncoated

The SLB-25.4-50N is a Plano-Concave Lens, a type of spherical lens, sourced from OptoSigma. This lens, with a diameter of 25.4 mm, is designed for use in systems where a negative focal length is required. The lens has a center thickness of 2 mm and an edge thickness of 5.3 mm, providing a robust structure suitable for various applications.

The lens's base shape is circular, and it has an effective focal length (EFL) of -50 mm, making it suitable for concave optical systems. The radius of curvature (R1) is -25.95 mm, and the back focal length (BFL) is -51.3 mm, indicating a strongly concave surface. The lens does not have an inner or outer radius, suggesting a uniform curvature across its surface.

The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The lens is uncoated, which may be suitable for applications where anti-reflective coatings are not necessary or desirable.

This lens is designed for use with a wavelength of 546.1 nm, making it suitable for applications in the visible light spectrum.
