67-454-INK 5.0mm Dia. x 7.5mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm

The 67-454-INK is a Plano-Convex lens with a 5.0mm diameter and a focal length of 7.5mm, sourced from the renowned optical components vendor, Edmund Optics. This lens is specifically designed for use in the Near-Infrared II (NIR II) spectrum, spanning wavelengths of 750-1550nm, making it ideal for applications requiring high-resolution imaging and sensing in this spectral range.

The lens is fabricated from N-SF11 Schott glass, a material known for its excellent optical properties and durability. The front and back surfaces of the lens are coated with the EDM NIR-II standard curve coating, enhancing its performance in the NIR II spectrum. This coating ensures high transmission rates and reduces surface reflections, thereby minimizing signal loss and improving overall system performance.

The lens geometry includes a 1.34mm edge thickness and a 1.9mm center thickness, providing robustness and structural integrity. The inner and outer radii are 0mm, indicating a simple spherical shape. The lens's effective focal length (EFL) is 7.5mm, and the back focal length (BFL) is 6.43mm, which are crucial parameters for designing optical systems.
