38-415-INK 18.0mm Dia. x 20.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 38-415-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 18.0mm, is designed for use in the near-infrared (NIR) spectrum, specifically between 750-1550nm, making it suitable for various applications in this range.
The lens features a front and back coating of edm nir-ii std curve, which is specifically designed for use in the NIR II spectrum. This coating enhances the lens' performance in this range, providing superior transmission and reducing unwanted reflections.
The geometry of the lens includes a thickness edge of 1.46mm and a thickness center of 4.3mm. The effective focal length (EFL) is 20.0mm, and the radius of curvature (R1) is 15.7mm. The back focal length (BFL) is 17.59mm, and both the inner and outer radii are 0mm.
The lens is made from n-sf11 schott, a material known for its excellent optical properties in the NIR spectrum. This material, combined with the lens' design and coating, makes the 38-415-INK an ideal choice for applications requiring high-performance NIR lenses.
According to the vendor's website, the lens is currently in stock, making it readily available for immediate use. For more information, users are encouraged to visit the provided weblink.
