SLB-25-35N 25.0 mm Dia. x -35.0 mm FL; Plano-Concave Lens Uncoated
The SLB-25-35N 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 with a wavelength of 546.1 nm.
The lens has a diameter of 25.0 mm and a thickness at the edge of 7.0 mm. The center thickness of the lens is 2.0 mm. The effective focal length (EFL) of the lens is -35.0 mm, indicating that it is a diverging lens. The radius of curvature (R1) of the lens is -18.17 mm, and the back focal length (BFL) is -36.3 mm. The lens does not have an inner or outer radius.
The lens is made of n-BK7 Schott, a common optical glass. This material is known for its excellent optical properties, making it suitable for a wide range of applications. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties.
The lens is currently in stock and can be purchased directly from the OptoSigma website. The link to the product page is provided for convenience.
