This is a Plano-Convex Lens, type 38-576, sourced from Edmund Optics. The lens has a circular base shape with a diameter of 12.0mm and a thickness of 1.22mm at the edge, increasing to 2.7mm at the center. The effective focal length (EFL) of this lens is 25mm.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The front and back surfaces of the lens are coated with YAG-BBAR, a type of anti-reflection coating that operates within the 500-1100nm wavelength range. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a plano surface on the non-curved side. The radius of curvature (R1) of the curved surface is 12.92mm, and the back focal length (BFL) is 32.22mm.
This lens is a versatile optical component, suitable for various applications within its specified wavelength range. It is currently in stock, as indicated by its weblink status. For more information or to make a purchase, please visit the provided weblink.
