SLB-25-30N 25.0 mm Dia. x -30.0 mm FL; Plano-Concave Lens Uncoated
The SLB-25-30N is a Plano-Concave Lens, a type of spherical lens, sourced from OptoSigma. This lens has a base shape of a circle and is uncoated. The lens is designed for use in the visible light spectrum, specifically at a wavelength of 546.1 nm.
The lens has a diameter of 25.0 mm and a thickness at the edge of 8.3 mm. The center thickness of the lens is 2.0 mm. The effective focal length (EFL) of the lens is -30.0 mm, indicating that it is a diverging lens. The radius of curvature of the first surface (R1) is -15.57 mm, and the back focal length (BFL) is -31.3 mm. The lens does not have any inner or outer radius.
The lens is made of n-BK7 Schott, a common optical glass with high homogeneity and low optical dispersion. This makes it suitable for a wide range of optical applications. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens is currently in stock and available for purchase. More information about this lens, including pricing and availability, can be found on the OptoSigma website.
