38-390-INK 9.0mm Dia. x 20mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 38-390-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 9.0mm, 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 2.44mm at the edge and 8mm at the center, with an effective focal length (EFL) of 250mm. The radius of curvature for the first surface (R1) is 129.2mm, and the back focal length (BFL) is 244.73mm. 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 circular in base shape, making it suitable for a wide range of applications.
The item data also indicates that the web link for this lens is valid and the lens is in stock, making it readily available for purchase and use.
