38-504 12.5mm Dia. x 25.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 38-504 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 12.5mm and a focal length of 25.0mm, 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, where one side is flat, and the other is curved. The curvature of the lens is defined by a radius of 12.92mm, and the back focal length is 22.96mm. The lens's edge thickness is 1.49mm, while the center thickness is 3.1mm, providing a robust structure for various applications.
The 38-504 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 400-1000nm. This makes the lens suitable for a wide range of applications, including spectroscopy, biomedical imaging, and machine vision systems.
