The 67-532-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 transmission and reducing unwanted reflections.
The lens has a thickness of 1.51mm at the edge and 3.0mm at the center. The effective focal length (EFL) of the lens is 54mm, making it suitable for a variety of optical applications. The lens' inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on the non-curved side.
The lens' radius of curvature (R1) is 27.91mm, and the back focal length (BFL) is 52.02mm. The lens is made from n-bk7 schott, a popular optical material known for its excellent optical properties and versatility.
The lens' web links are valid and indicate that it is currently in stock, making it readily available for immediate use. This lens is a great option for anyone looking for a high-quality, NIR II compatible Plano-Convex lens.
