38-401-INK 12.5mm Dia. x 25.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type Spherical, with a circular base shape, sourced from the renowned optical vendor, Edmund Optics. The lens is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for the wavelength of 587.6nm.
The lens has a diameter of 12.5mm and a thickness at the edge of 1.4mm, which gradually increases to 3.5mm at the center. The effective focal length (EFL) of the lens is 20mm. The first radius of curvature (R1) is 10.34mm, and the back focal length (BFL) is 17.69mm. The lens does not have any inner or outer radius.
The lens is made of N-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces, ensuring optimal performance in the NIR II spectrum, specifically between 750-1550nm.
