67-501-INK 12.0mm Dia. x 48.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-501-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 II (NIR II) spectrum, specifically for wavelengths between 750 and 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 image quality and light transmission.
The lens has a thickness of 1.85mm at the edge and 2.7mm at the center. The effective focal length (EFL) of the lens is 42mm, making it suitable for a variety of optical applications. The lens also has a relatively large back focal length (BFL) of 40.22mm, which can be beneficial in certain optical system designs.
The lens is made from n-bk7 schott, a high-quality optical glass that offers excellent optical performance. The lens is inked, which is a process that adds a layer of ink to the edge of the lens to protect it during handling and storage.
