The 48-749-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 15.0mm, 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 thickness of 1.13mm at the edge and 2.05mm at the center, with an effective focal length (EFL) of 60mm. The radius of curvature for the first surface (R1) is 31.11mm, and the back focal length (BFL) is 58.65mm. The lens is made of n-bk7 schott, a popular material for optical elements due to its excellent optical properties.
The lens is inked, a process that involves applying a dye to the edge of the lens to indicate its orientation. This is particularly useful in applications where the lens may be installed in a system where the orientation is not immediately apparent.
The lens is available directly from Edmund Optics and is currently in stock, according to the vendor's website. For more detailed information, including technical drawings and performance data, please refer to the product page on the Edmund Optics website.
