The 66-260 is a Plano-Convex Spherical Lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a 6.0mm diameter and a 9.0mm focal length, making it suitable for a wide range of optical applications.
The lens is crafted from n-SF5 Schott, a high-quality optical material known for its excellent transmission properties and durability. The base shape of the lens is circular, ensuring uniform light distribution and minimal distortion.
The geometry of the lens is meticulously designed, with a thickness of 0.95mm at the edge and 1.75mm at the center. The effective focal length (EFL) is 9mm, and the radius of curvature (R1) is 6.05mm. The back focal length (BFL) is 7.95mm, and both the inner and outer radii are 0mm, indicating a uniform curvature.
The lens is coated with Edmund Optics' Las V-Coat 633, a specialized coating designed to enhance laser performance at a wavelength of 633nm. This coating ensures high transmission, low reflectivity, and increased durability, making the lens ideal for laser applications.
