The 45-127 25.0mm Dia. x 60.0mm FL is a Plano-Convex lens, uncoated, sourced from the renowned optical components vendor, Edmund Optics. This lens, with a base shape of a circle, is a Spherical Lens subtype, designed for specific optical applications.
The lens has a diameter of 25.0mm and a center thickness of 4.7mm, with an edge thickness of 2.07mm. The Effective Focal Length (EFL) of this lens is 60.0mm, making it suitable for applications that require a longer focal length. The lens's first radius of curvature (R1) is 31.01mm, and the back focal length (BFL) is 56.9mm. The lens does not have any coating, as indicated by the 'uncoated' term in its name.
The lens is made of N-BK7 Schott material, a popular choice in the optical industry due to its excellent optical properties. The lens is designed to operate at a wavelength of 587.6nm.
Please note that the lens's inner and outer radii are both zero, indicating that this lens is a Plano-Convex lens, where one surface is flat (plano) and the other is curved (convex).
