38-406-INK 12.5mm Dia. x 50.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 38-406-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.5mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750nm and 1550nm.
The lens features a front and back coating of EDM NIR-II STD CURVE, which is a standard coating for NIR II applications. This coating enhances the lens' performance in the NIR II spectrum, ensuring optimal functionality in its intended use.
The lens has a thickness of 1.14mm at the edge and 2mm at the center. The effective focal length (EFL) of the lens is 45mm, and the radius of curvature (R1) is 23.26mm. The back focal length (BFL) is 43.68mm, and the lens does not have any inner or outer radius.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. This material is known for its high Abbe number, low refractive index, and low dispersion, making it ideal for a wide range of optical applications.
