This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 38-581-INK, is characterized by its circular base shape and spherical geometry. The lens's diameter measures 12.5mm, and it has a thickness of 1.4mm at the edge, increasing to 3.5mm at the center. The effective focal length (EFL) is 20mm, and the radius of curvature (R1) is 10.34mm. The back focal length (BFL) is 17.69mm, and both the inner and outer radii are 0mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens's coating is YAG-BBAR, which is designed for use in the 500-1100nm wavelength range. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it suitable for various applications.
