67-489-INK 10.0mm Dia. x 40.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-489-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 10.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically between 750-1550nm.
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 region, providing superior transmission and reducing unwanted reflections.
The lens has a thickness of 2.17mm at the edge and 3.0mm at the center. The effective focal length (EFL) of the lens is 30mm, making it suitable for a variety of optical applications. The lens's front surface has a radius of curvature (R1) of 15.5mm, while the back focal length (BFL) is 28.01mm.
The lens is made from n-bk7 schott, a popular optical material known for its excellent optical properties and versatility. This material ensures high transmission and low dispersion, making it ideal for use in the NIR II spectrum.
