40.0mm Dia. x 300.0mm FL Plano-Convex Lens with VIS 0° Coating
This item is a 40.0mm diameter x 300.0mm focal length plano-convex lens, sourced from the renowned optical vendor, Edmund Optics. The lens is designed for use within the visible light spectrum, specifically at a wavelength of 587.6nm.
The lens is fabricated from the high-quality material, N-BK7 Schott, which is known for its excellent optical properties and durability. The plano-convex geometry of the lens, where one side is flat and the other is curved, allows for efficient light transmission and focusing.
The lens features a front and back coating of EDM VIS-0 STD CURVE, which is a broadband anti-reflection coating designed for use within the visible spectrum. This coating reduces surface reflections, thereby enhancing the overall transmission of light through the lens.
The lens has a center thickness of 5.0mm and an edge thickness of 3.7mm, providing a robust structure while maintaining a relatively lightweight design. The inner and outer radii are both 0mm, indicating a uniform curvature across the lens surface.
The lens's effective focal length (EFL) is 300.0mm, which is the distance from the lens's principal point to the point where the lens brings the light to a focus. The back focal length (BFL) is 296.7mm, which is the distance from the lens's rear surface to the point of focus.
