The 48-756-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 18.0mm, is designed for use in the near-infrared (NIR) spectrum, specifically between 600-1050nm. The lens features a front and back coating of edm nir-i std curve, providing enhanced performance in the NIR range.
The lens has a focal length (FL) of 72.0mm, which is the distance between the lens and the point where the light rays converge. The edge thickness of the lens is 1.9mm, while the center thickness is 3.0mm. The effective focal length (EFL) is 72.05mm, and the radius of curvature (R1) is 37.22mm. The back focal length (BFL) is 70.05mm.
The lens is made from n-bk7 schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is circular in base shape and has no inner or outer radius, indicating a uniform curvature throughout.
The lens's coating and material make it suitable for various applications within the NIR spectrum, such as spectroscopy, thermal imaging, and night vision systems. The 48-756-INK is currently in stock, according to the vendor's website, making it readily available for immediate use.
