49-179 3.0mm Dia. x 12.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 49-179 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 3.0mm and a focal length of 12.0mm, making it a compact yet powerful optical component. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a plano-convex geometry, meaning one side is flat (plano) while the other is curved (convex). The curvature of the convex side is defined by a radius of 6.2mm. The lens's edge thickness is 0.9mm, while the center thickness is 1.08mm, providing a balanced structure for efficient light transmission.
The 49-179 lens is coated with edm visnir0sp2002000 on both the front and back surfaces. This coating enhances its performance in the visible (VIS) and near-infrared (NIR) spectrum, specifically between 400 and 1000nm. This makes the lens suitable for a wide range of applications, including spectroscopy, biomedical imaging, and machine vision.
