67-456-INK 5.0mm Dia. x 12.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-456-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 5.0mm, is designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm, as indicated by its NIR II coating.
The lens's geometry is characterized by its edge thickness of 1.25mm and center thickness of 1.77mm. It has an effective focal length (EFL) of 12mm, making it suitable for various optical applications. The lens's front radius of curvature (R1) is 6.22mm, and its back focal length (BFL) is 10.83mm. The lens's inner and outer radii are both 0mm, indicating a uniform curvature.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The lens's coating, edm nir-ii std curve, is applied to both the front and back surfaces, enhancing its performance in the NIR spectrum.
