67-547-INK 25.0mm Dia. x 60.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-547-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.0mm, 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, providing optimal performance within its specified wavelength range.
The lens has a thickness of 2mm at the edge and 7.01mm at the center, with an effective focal length (EFL) of 35mm. The radius of curvature for the first surface (R1) is 18.11mm, and the back focal length (BFL) is 30.42mm. The lens is made of N-BK7 Schott material, a popular choice for its high refractive index and low dispersion.
