SLB-30-80N 30.0 mm Dia. x -80.0 mm FL; Plano-Concave Lens Uncoated
The SLB-30-80N is a Plano-Concave Lens, part of the Spherical Lens family, sourced from OptoSigma. This lens is uncoated and features a base shape of Circular. The lens has a diameter of 30.0 mm and a thickness edge of 4.8 mm, with a center thickness of 2.0 mm. The effective focal length (EFL) of this lens is -80.0 mm, making it a negative or diverging lens.
The lens's inner radius is 0 mm, and the outer radius is also 0 mm, indicating a uniform curvature. The first radius of curvature (R1) is -41.52 mm, and the back focal length (BFL) is -81.3 mm. The material used for this lens is n-BK7 Schott, a common material in optical applications due to its excellent optical properties.
This lens is designed to operate at a wavelength of 546.1 nm. The absence of a coating suggests that this lens is intended for use in applications where the introduction of a coating might interfere with the desired optical properties.
