33-369-INK 25.0mm Dia. x 400.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm

This is a Plano-Convex lens, type of spherical lens, with a circular base shape and a diameter of 25.0mm. The lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock. The lens features a thickness of 2.44mm at the edge and 3.2mm at the center, with an effective focal length (EFL) of 200mm. The front and back surfaces of the lens are coated with the EDM NIR-II standard curve coating, optimized for the near-infrared (NIR) spectrum, specifically for the 750-1550nm range. The lens is made of N-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a plano surface on the incident side. The back focal length (BFL) of the lens is 197.89mm.
