SLB-50.8-80N 50.8 mm Dia. x -80.0 mm FL; Plano-Concave Lens Uncoated
The SLB-50.8-80N is a Plano-Concave Lens, part of OptoSigma's extensive range of uncoated spherical lenses. This lens has a base shape of a circle and a diameter of 50.8 mm, making it suitable for a wide range of optical applications. The lens's thickness at the edge is 11.7 mm, while the center thickness is 3 mm, providing a robust structure.
The effective focal length (EFL) of this lens is -80 mm, indicating its concave nature. The radius of curvature (R1) is -41.52 mm, and the back focal length (BFL) is -82 mm. The lens's inner and outer radii are both 0 mm, suggesting a uniform curvature throughout.
The lens is made of n-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. The wavelength for this lens is 546.1 nm. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, uncoated lenses can be more cost-effective and are often used in applications where specific coating is not required.
