SLB-40-100N 40.0 mm Dia. x -100.0 mm FL; Plano-Concave Lens Uncoated

The SLB-40-100N is a Plano-Concave Lens, part of the Spherical Lens category, sourced from OptoSigma. This lens is characterized by its 40.0 mm diameter and a focal length of -100.0 mm, making it a negatively powered lens. The lens is uncoated, which means it does not have any anti-reflective or other surface coatings.

The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high homogeneity. The geometry of the lens includes a thickness of 6 mm at the edge and 2 mm at the center, with an inner radius and outer radius of 0 mm, indicating a flat surface on both sides. The radius of curvature (R1) is -51.9 mm, and the back focal length (BFL) is -101.3 mm.

This lens is designed to operate at a wavelength of 546.1 nm, typically used in monochromatic light applications. The lens is suitable for use in various optical systems, including beam expanders, laser systems, and imaging systems, where a negative lens is required.

Please note that the lens is uncoated, which may result in unwanted reflections. However, this can be mitigated by adding an anti-reflective coating, which is not included in this product but can be requested separately.
