The 49-909-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 1.26mm at the edge and 2.5mm at the center, with an effective focal length (EFL) of 45.0mm. The radius of curvature for the first surface (R1) is 23.26mm, and the back focal length (BFL) is 43.35mm. The lens is made from n-bk7 schott, a common material for optical lenses due to its excellent optical properties.
The lens is designed for use at a wavelength of 587.6nm, and it has an inner radius of 0mm and an outer radius of 0mm. The lens's base shape is circular, making it suitable for a wide range of applications.
