65-298 2.0mm Dia. x 3.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm

The 65-298 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 2.0mm 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 excellent optical properties.

The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating that enhances its performance in the visible to near-infrared spectrum, specifically between 400-1000nm. This coating ensures high transmission and low reflection, making it ideal for applications that require high-quality imaging or light transmission.

The lens's geometry includes a thickness of 0.6mm at the edge and 0.8mm at the center, with an effective focal length (EFL) of 3.0mm. The radius of curvature (R1) is 2.55mm, and the back focal length (BFL) is 2.57mm. The lens's base shape is circular, and it does not have any inner or outer radius, indicating a flat surface on the uncoated side.
