67-555-INK 25.0mm Dia. x 250.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type of spherical lens, sourced from Edmund Optics. The lens has a circular base shape with a diameter of 25.0mm and a thickness at the edge of 2.49mm, while the center thickness is 3.5mm. The effective focal length (EFL) of the lens is 150mm, and the radius of curvature (R1) is 77.55mm. The back focal length (BFL) is 147.81mm, and 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. It is designed to work with a wavelength of 587.6nm. The lens features a front and back coating of EDM NIR-II STD CURVE, a specialized coating for Near-Infrared II (NIR II) applications, which provides high transmission in the 750-1550nm range.
