SLB-30-90N 30.0 mm Dia. x -90.0 mm FL; Plano-Concave Lens Uncoated

The SLB-30-90N is a Plano-Concave Lens, part of the Spherical Lens family, sourced from OptoSigma. This lens is uncoated and features a base shape of a circle, with a diameter of 30.0 mm and a thickness edge of 4.5 mm. The lens's center thickness is 2.0 mm, and it has an effective focal length (EFL) of -90.0 mm.

The lens's concave surface has a radius of curvature (R1) of -46.71 mm, and the back focal length (BFL) is -91.3 mm. The lens does not have any inner or outer radii, indicating a uniform curvature.

The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is designed to operate at a wavelength of 546.1 nm.

The item data does not provide information about any coatings on the lens. Therefore, it is safe to assume that the lens is uncoated, which may affect its transmission and reflection properties.
