This is a Plano-Convex lens, type 48-233-INK, sourced from Edmund Optics. The lens has a base shape of a circle and is designed for use within the visible light spectrum, specifically at a wavelength of 587.6nm. The lens is made from n-SF5 Schott material, a high-index glass often used in optical applications due to its excellent transparency and low auto-fluorescence.
The lens has a diameter of 30.0mm and a thickness at the edge of 2.82mm, transitioning to a thickness at the center of 6.35mm. The effective focal length (EFL) of the lens is 50.0mm, making it suitable for applications requiring a longer focal length. The front and back surfaces of the lens are coated with the EDM VIS-0 standard curve coating, which provides excellent broadband anti-reflection performance from 425-675nm.
The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a plano surface on the incident side. The radius of curvature of the lens is 33.63mm on the exiting side. The back focal length (BFL) of the lens is 46.17mm.
