The 67-558-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.0mm, 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 transmission and reducing unwanted reflections.
The lens has a thickness of 2.39mm at the edge and 3.0mm at the center. The effective focal length (EFL) of the lens is 250mm, making it suitable for a variety of optical applications. The front surface of the lens has a radius of curvature of 129.2mm, and the back focal length (BFL) is 248.02mm.
The lens is made from n-bk7 schott, a popular optical material known for its excellent optical properties and high damage threshold. This material ensures the lens delivers high-quality images with minimal distortion.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://www.edmundoptics.com/f/nir-ii-coated-plano-convex-pcx-lenses/14105/.
