The 65-534 is a Plano-Convex spherical lens, boasting a 9.0mm diameter and a focal length of 9.0mm, specifically designed for use with a wavelength of 1064nm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is constructed from n-SF11 Schott, a high-index glass with excellent transmittance in the near-infrared region, making it ideal for use in laser applications. The lens features a front and back coating of Edmund Optics' Laser V-Coat 1064, which is designed to enhance the lens's performance in laser applications by reducing reflection and increasing transmission.
The lens has a thickness of 1.38mm at the edge and 3.0mm at the center, providing a balanced profile for efficient light transmission. The inner and outer radii are both 0mm, indicating a uniform curvature across the lens's surface. The lens's effective focal length (EFL) is 9.0mm, which, combined with its 9.0mm diameter, results in a high numerical aperture (NA) for efficient light collection and focusing.
