65-281 2.0mm Dia. x 2.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
The 65-281 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 2.0mm, making it a compact and powerful optical component. The lens is made from n-lasf9 Schott, a material known for its high optical quality.
The lens features a standard VIS 0° coating on both the front and back surfaces, enhancing its performance in the visible light spectrum, specifically between 425-675nm. This coating helps to reduce reflection and increase transmission, making the lens ideal for applications that require high light transmission and minimal loss.
The geometry of the lens includes a thickness of 0.48mm at the edge and 0.8mm at the center. The inner radius is 0, while the outer radius is also 0, indicating a flat surface on the non-curved side of the lens. The effective focal length (EFL) is 2.0mm, and the back focal length (BFL) is 1.57mm.
