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 35.0mm and a thickness at the edge of 1.45mm, while the center thickness is 4.5mm. The effective focal length (EFL) of the lens is 100.0mm, making it suitable for a variety of optical applications. The lens features a front and back coating of edm nir-ii std curve, which enhances its performance in the NIR II spectrum.
The lens has an inner radius of 0mm and an outer radius of 0mm, with a front radius (R1) of 51.68mm and a back focal length (BFL) of 97.03mm. The lens is made of n-bk7 schott material, a common choice for its high refractive index and low dispersion.
The lens is currently in stock and available for purchase through the Edmund Optics website, as indicated by the 'weblink status' field in the item data.
