45-502-INK 20.0mm Dia. x 60.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-502-INK is a plano-convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically between 400-1000nm.
The lens has a center thickness of 4.5mm and an edge thickness of 2.84mm, providing a base shape that is circular. The effective focal length (EFL) of this lens is 60.0mm, and the front and back surfaces have a radius of curvature of 31.01mm and 57.03mm respectively.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is coated with edm visnir0sp2002000 on both the front and back surfaces, enhancing its performance in the VIS-NIR spectrum.
This lens is a valuable addition to any optical system that operates within its specified spectrum. Its plano-convex design and VIS-NIR coating make it suitable for a wide range of applications, including but not limited to, imaging, beam shaping, and light collimation.
