SLB-25.4-50PM 25.4 mm Dia. x 50.0 mm FL; Coated; Plano-Convex Lens 400-700nm
This is a Plano-Convex lens, type SLB-25.4-50PM, sourced from OptoSigma. The lens has a base shape of a circle and is designed for use within a wavelength range of 400-700nm. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The lens has a diameter of 25.4mm and a thickness at the edge of 1.9mm. The center thickness is 5.2mm, and the effective focal length (EFL) is 50mm. The radius of curvature for the first surface (R1) is 25.95mm, and the back focal length (BFL) is 46.6mm. The lens does not have any inner or outer radius specified, indicating a uniform curvature.
The lens features a coating on both the front and back surfaces. The coating is Opt M, which is known for its excellent transmission properties and durability. This coating enhances the lens' performance in the specified wavelength range.
