67-538-INK 20.0mm Dia. x 70.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-538-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750nm 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 2.32mm at the edge and 4.9mm at the center. The effective focal length (EFL) of the lens is 40mm, making it suitable for a variety of optical applications. The lens' front radius of curvature (R1) is 20.67mm, and the back focal length (BFL) is 36.77mm.
The lens is made from n-bk7 schott, a high-quality optical glass that offers excellent optical performance. The lens is circular in shape, making it compatible with a wide range of optical systems.
The lens' web link status is valid and it is currently in stock, making it readily available for immediate use. This lens is an excellent choice for anyone looking for a high-quality, NIR II compatible Plano-Convex lens.
