38-394-INK 12.0mm Dia. x 25mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm

The 38-394-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, is designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. The lens features a front and back coating of edm nir-ii std curve, which enhances its performance in the NIR spectrum.

The lens has a thickness of 1.29mm at the edge and 2.8mm at the center. The effective focal length (EFL) of this lens is 17.5mm, and its radius of curvature (R1) is 9.05mm. The back focal length (BFL) of the lens is 15.66mm. The lens is made of n-bk7 schott, a material known for its excellent optical properties.

The lens is inked, which is a process that adds a dye or pigment to the surface of the lens. This can be done for a variety of reasons, such as to mark the lens for identification or to reduce reflections. The lens is available for purchase directly from the vendor's website, where it is listed as being in stock.
