The 38-542 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 25.4mm and a focal length of 40.0mm, making it suitable for a variety of applications. 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 front and back coating of edm visnir0sp2002000, a VIS-NIR coating designed for use in the visible and near-infrared spectrum (400-1000nm). This coating enhances the lens's performance by reducing surface reflections and increasing transmission, making it ideal for use in demanding optical systems.
The lens's geometry includes a thickness edge of 1.54mm and a thickness center of 5.9mm. The inner radius is 0mm, and the outer radius is also 0mm. The lens's base shape is circular, and its shape is spherical.
