67-563 25.4mm Dia. x 63.5mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex Lens, specifically designed for use in the Near-Infrared II (NIR II) spectrum, with a diameter of 25.4mm and a focal length of 63.5mm. The lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made from n-SF11 Schott, a material well-suited for NIR applications due to its low auto-fluorescence and high damage threshold. The lens geometry includes a diameter of 25.4mm, a thickness at the edge of 2.43mm, and a thickness at the center of 7mm. The effective focal length (EFL) is 25.4mm, and the radius of curvature (R1) is 19.93mm. The back focal length (BFL) is 21.48mm, and both the inner and outer radii are 0mm.
The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces, designed to optimize performance in the 750-1550nm wavelength range. This coating enhances transmission and reduces reflection, ensuring optimal performance in NIR II applications.
