This is a Plano-Convex lens, type of spherical lens, with a circular base shape and a diameter of 25.0mm. The lens has a thickness of 2.28mm at the edge and 3.5mm at the center, with an effective focal length (EFL) of 125mm. The front and back surfaces of the lens are coated with edm nir-ii std curve, a specialized coating for Near-Infrared II (NIR II) applications, which covers the wavelength range of 750-1550nm. The lens is sourced from Edmund Optics, a leading vendor in the optical industry, and is currently in stock with a valid web link for direct purchase. The lens is designed for use in NIR II applications, making it an ideal choice for researchers and engineers working in this field.
