65-280 2.0mm Dia. x 1.5mm FL; VIS 0° Coated; Plano-Convex Lens VIS 0° 425-675nm
The 65-280 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. It boasts a 2.0mm diameter and a 1.5mm focal length, making it suitable for a variety of applications. The lens is made from n-lasf9 Schott, a material known for its high refractive index and low dispersion, ensuring excellent image quality.
The lens features a standard VIS 0° coating on both the front and back surfaces, enhancing its transmission capabilities within the 425-675nm visible light spectrum. This coating helps reduce surface reflections, improving light transmission and overall image quality.
The geometry of the lens is well-defined, with a 0.32mm edge thickness and a 0.8mm center thickness. The lens's effective focal length (EFL) is 1.5mm, and its radius of curvature (R1) is 1.28mm. The back focal length (BFL) is 1.07mm, and both the inner and outer radii are 0mm, indicating a flat surface on the lens's entry side.
