47-381-INK 6.0mm Dia. x 48.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 47-381-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 6.0mm, is designed for use within the visible to near-infrared spectrum, specifically between 400-1000nm. The lens has a front focal length (FL) of 48.0mm, making it suitable for a variety of optical applications.
The lens is coated with a VIS-NIR coating, denoted as edm visnir0sp2002000, on both the front and back surfaces. This coating enhances the lens's performance within the specified wavelength range. The lens's center thickness is 1.6mm, while the edge thickness is 1.42mm, providing a robust structure for the lens.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature. The back focal length (BFL) is 46.95mm, and the effective focal length (EFL) is 48mm. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
