45-470-INK 6.0mm Dia. x 21.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-470-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 focal length of 21.0mm, indicated by the 'FL' in its name, and is inked for ease of identification and handling.
The lens's geometry is defined by its edge thickness of 1.0mm and center thickness of 1.42mm. The front surface radius (R1) is 10.85mm, and the back focal length (BFL) is 20.06mm. The lens's inner and outer radii are both 0mm, indicating a uniform curvature.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is coated with 'edm visnir0sp2002000' on both the front and back surfaces, a coating designed for visible to near-infrared applications.
