67-486-INK 10.0mm Dia. x 20.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm

This product is a Plano-Convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens is designed for use in the Near-Infrared II (NIR II) spectrum, specifically catering to the wavelength range of 750-1550nm.

The lens features a circular base shape with a diameter of 10.0mm, making it suitable for a wide range of applications. The lens has a thickness of 1.89mm at the edge, increasing to 3.0mm at the center, providing a robust structure for various optical setups.

The effective focal length (EFL) of this lens is 15mm, which is a common choice for many optical systems due to its versatility. The first radius of curvature (R1) is 11.77mm, and the back focal length (BFL) is 13.32mm, offering a well-balanced optical performance.

The lens is made from N-SF11 Schott, a high-index glass material that is known for its excellent optical properties. This material is particularly suitable for NIR applications due to its low autofluorescence and high transmission in the NIR range.

The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the NIR II spectrum, providing improved transmission and reduced reflection.
