The 38-404-INK 12.5mm Dia. x 40.0mm FL; NIR II; Inked; Plano-Convex Lens is a high-quality optical component sourced from Edmund Optics. This lens is specifically designed for use in the near-infrared (NIR) spectrum, with a wavelength range of 750-1550nm, making it ideal for a wide range of applications in this spectral region.
The lens is spherical in shape, with a base shape of circular, and features a plano-convex geometry. The diameter of the lens is 12.5mm, and it has a thickness of 1.29mm at the edge, increasing to 2.4mm at the center. The effective focal length (EFL) of the lens is 35mm, and the radius of curvature (R1) is 18.09mm. The back focal length (BFL) is 33.42mm, and both the inner and outer radii are 0mm.
The lens is made from N-BK7 Schott, a popular optical material known for its excellent optical properties and high damage threshold. The lens is coated with the EDM NIR-II std curve on both the front and back surfaces, which enhances its performance in the NIR spectrum.
