65-302 2.5mm Dia. x 3.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 65-302 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 2.5mm and a focal length of 3.0mm, making it a compact and efficient optical component. The lens is made from n-lasf9 Schott, a material known for its high optical quality and durability.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). The radius of curvature for the convex side is 2.55mm, and the back focal length is 2.57mm. The lens has an edge thickness of 0.47mm and a center thickness of 0.8mm, providing a solid structure for various applications.
The 65-302 lens is coated with edm visnir0sp2002000 on both the front and back surfaces. This coating enhances its performance in the visible to near-infrared spectrum, specifically between 400-1000nm. The coating ensures high transmission, low reflectance, and increased durability, making it suitable for use in a wide range of optical systems.
