This product is a Plano-Convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 47-342-INK, boasts a diameter of 25.0mm and a focal length of 25.0mm, making it a versatile choice for various optical applications.
The lens is constructed from Schott's n-SF5 material, a high-index glass known for its excellent optical properties. The base shape of the lens is circular, and it features a plano-convex geometry, with the convex side facing outwards. The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature throughout.
The lens's thickness at the edge is 2.43mm, while the center thickness is 8mm, providing a balanced profile for efficient light transmission. The effective focal length (EFL) of the lens is 25mm, and the radius of curvature (R1) is 16.82mm. The back focal length (BFL) is 20.22mm.
The lens is coated with Edmund Optics' standard VIS-0 coating on both the front and back surfaces. This coating is designed for visible light with a wavelength of 587.6nm, ensuring optimal light transmission within the spectral range of 425-675nm. The coating also provides excellent environmental stability and resistance to scratching and abrasion.
