The 66-254 is a Plano-Convex spherical lens, boasting a 6.0mm diameter and a 9.0mm focal length. This lens is sourced from the renowned optical vendor, Edmund Optics, and is designed for use with a 405nm wavelength. The lens is fabricated from n-SF5 Schott material, a high-index glass renowned for its excellent optical properties.
The lens features a plano-convex geometry, where one side is flat, and the other side is curved. This design allows for a broad range of applications, including laser focusing and imaging systems. The lens has a center thickness of 1.75mm and an edge thickness of 0.95mm, providing robustness and durability.
The 66-254 lens is coated with Edmund Optics' proprietary Laser V-Coat 405, a high-performance coating specifically designed for 405nm applications. This coating enhances the lens's performance by reducing surface reflections and improving transmission. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
