65-284 2.5mm Dia. x 2.0mm FL; VIS 0° Coated; Plano-Convex Lens VIS 0° 425-675nm
The 65-284 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. It boasts a 2.5mm diameter and a 2.0mm focal length, making it a compact and efficient optical component. The lens is made from n-lasf9 Schott, a material known for its high refractive index and low dispersion, ensuring excellent image quality and color correction.
The lens features a standard VIS 0° coating on both the front and back surfaces. This coating enhances the lens's transmission in the visible spectrum, specifically between 425-675nm, and reduces surface reflections, thereby increasing the overall system efficiency. The front surface of the lens has a 1.7mm radius of curvature, while the back surface has a 1.57mm radius, contributing to its plano-convex shape.
The lens's effective focal length (EFL) is 2mm, and its back focal length (BFL) is 1.57mm. The edge thickness of the lens is 0.25mm, while the center thickness is 0.8mm. The lens is circular in base shape, and its geometry is designed for optimal performance in various optical systems.
