45-495 18.0mm Dia. x 27.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-495 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts an 18.0mm diameter and a 27.0mm focal length, making it suitable for a wide range of applications. The lens is made from n-sf5 Schott, a high-quality optical material known for its excellent transmittance and durability.
The lens features a Plano-Convex geometry, where one side is flat, and the other side is curved. The curvature of the lens is defined by a radius of 18.16mm, and the back focal length is 24.73mm. The lens has a central thickness of 3.8mm and an edge thickness of 1.41mm, providing a robust structure for various optical systems.
The 45-495 lens is coated with edm visnir0sp2002000 on both the front and back surfaces. This coating enhances its performance in the visible and near-infrared spectrum, specifically between 400-1000nm. The coating ensures high transmittance, low reflectance, and resistance to environmental factors, making it ideal for applications in imaging, spectroscopy, and beam shaping.
