SLSQ-30-40N 30.0 mm Dia. x -40.0 mm FL; Plano-Concave Lens Uncoated
The SLSQ-30-40N is a Plano-Concave Lens, a type of spherical lens, sourced from OptoSigma. This lens is characterized by its fused silica material, denoted as "fused sil mal-1965" in the item data, and its uncoated surface. The lens has a base shape of a circle, with a diameter of 30.0 mm.
The lens's geometry includes a thickness edge of 9.7 mm and a thickness center of 2.0 mm. The effective focal length (EFL) is -40.0 mm, indicating that it is a diverging lens. The radius of curvature (R1) is -18.4 mm, and the back focal length (BFL) is -41.4 mm. The lens does not have any inner or outer radii, indicating a simple plano-concave design.
The lens is designed to operate at a wavelength of 546.1 nm. The shape of the lens is spherical, a common type of lens used in various optical applications due to its ease of manufacturing and versatility. The coating of the lens is not specified in the item data, indicating that it is likely uncoated.
