SBX052 50.8 mm Dia. x 75.6 mm FL; Uncoated; Double-Convex Lens
The SBX052 is a spherical lens with a base shape of a circle, sourced from the reputable vendor MKS/Newport. This lens is uncoated, making it suitable for applications where coating is not a requirement. The lens is designed for use in the visible light spectrum, specifically at a wavelength of 589 nm.
The lens has a diameter of 50.8 mm and a thickness at the edge of 3 mm. The center thickness of the lens is 12.954 mm. The effective focal length (EFL) of the lens is 75.6 mm, which is the distance from the lens's secondary principal plane to the focal point when the lens is imaging an object at infinity.
The first radius of curvature (R1) of the lens is 67.302 mm, while the second radius of curvature (R2) is -67.302 mm. The back focal length (BFL) of the lens is 71.02 mm, which is the distance from the rear surface of the lens to the secondary principal plane. The lens does not have an inner radius or an outer radius.
The lens is made of UVFS material with the ID 1965. This material is known for its excellent optical properties, making it suitable for a wide range of applications. The lens is designed to be used in a double-convex configuration, which means it has two convex surfaces.
