47-340 12.0mm Dia. x 84.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
This is a 12.0mm diameter, 84.0mm focal length Plano-Convex lens, specifically designed for the visible light spectrum (425-675nm). The lens is sourced from Edmund Optics, a leading provider of optical components.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes the lens suitable for a wide range of applications where high image quality and low distortion are required.
The lens features a standard Vis-0 coating on both the front and back surfaces. This coating is designed to enhance the lens's transmission in the visible spectrum, reducing surface reflections and improving overall light transmission. The coating also provides protection against environmental factors, ensuring the lens maintains its performance over time.
The geometry of the lens includes a 2.08mm edge thickness and a 2.5mm center thickness. The lens's effective focal length (EFL) is 84mm, and the back focal length (BFL) is 82.39mm. The lens's inner and outer radii are 0, indicating a planar surface on one side and a curved surface on the other.
