The 65-301 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 2.5mm, making it a compact and efficient optical component. The lens is made from n-lasf9 schott, a material known for its optical properties.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating suitable for use in the visible and near-infrared spectrum, specifically designed for applications within the 400-1000nm range. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, making it ideal for use in various optical systems.
The lens's geometry includes a thickness of 0.39mm at the edge and 0.8mm at the center, with an effective focal length (EFL) of 2.5mm. The lens's inner and outer radii are 0, indicating a flat surface on one side and a curved surface on the other. The radius of curvature (R1) is 2.12mm, and the back focal length (BFL) is 2.05mm.
