38-387-INK 6.0mm Dia. x 20mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 38-387-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 6.0mm, 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 is specifically designed for NIR applications. This coating enhances the lens' performance in the NIR spectrum, providing superior transmission and reducing unwanted reflections.
The lens has a thickness of 3.66mm at the edge and 32.62mm at the center. The effective focal length (EFL) of the lens is 75mm, making it suitable for applications that require a long focal length. The lens's front radius of curvature (R1) is 38.76mm, and the back focal length (BFL) is 53.49mm.
The lens is made from n-bk7 schott, a popular optical glass known for its excellent optical properties and high Abbe number. This material ensures high transmission in the visible and NIR spectra, making it ideal for a wide range of applications.
The lens is inked, which is a process that adds a dye to the lens to make it more visible and easier to handle. This feature is particularly useful in production environments where lenses need to be quickly identified and sorted.
