The 45-467-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 in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to wavelengths between 400 and 1000nm.
The lens features a front and back coating of edm visnir0sp2002000, which is a broadband anti-reflection coating optimized for the VIS-NIR range. This coating aids in minimizing surface reflections, thereby enhancing the overall transmission of light through the lens.
The lens's geometry includes a thickness of 0.83mm at the edge and 1.6mm at the center, with an effective focal length (EFL) of 12mm. The radius of curvature for the first surface (R1) is 6.2mm, and the back focal length (BFL) is 10.94mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The lens is inked, which is a process where a dye is applied to the edge of the lens to indicate its orientation. This is particularly useful during assembly to ensure the correct orientation of the lens.
