SLB-25.4B-100N 25.4 mm Dia. x -99.7 mm FL; Double-Concave Lens Uncoated

The SLB-25.4B-100N is a high-quality double-concave lens offered by OptoSigma, a leading vendor in the optical industry. This lens, designed with a base shape of a circle, is specifically engineered for use in a wide range of optical applications.

The lens boasts a diameter of 25.4 mm and a thickness at the edge of 3.6 mm, ensuring durability and robustness. The center thickness is a mere 2 mm, contributing to its overall sleek design. The effective focal length (EFL) of this lens is -99.7 mm, making it suitable for applications requiring strong negative magnification.

The SLB-25.4B-100N is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties. The radii of curvature for this lens are -103.8 mm for the first surface and 103.8 mm for the second surface, which are both uncoated. The back focal length (BFL) is -100.4 mm, and the lens does not have any inner or outer radius, indicating a uniform curvature.

This lens is designed to work with a wavelength of 546.1 nm, a standard yellow-green line in the visible spectrum, often used in interferometry and other optical testing applications. The lens is spherical in shape, a common choice for its ease of manufacturing and versatility.
