The 67-448 is a Plano-Convex lens with a diameter of 4.0mm and a focal length of 8.0mm, specifically designed for use in the Near-Infrared II (NIR II) spectrum, covering the wavelength range of 750-1550nm. This lens is sourced from the reputable optical vendor, Edmund Optics.
The lens is made from the high-quality material n-Baf10 Schott, which is known for its excellent optical properties in the NIR spectrum. The lens geometry includes a thickness of 1.0mm at the edge and 1.39mm at the center, with a back focal length of 7.17mm and an effective focal length of 8.0mm. The lens has a spherical shape, with a radius of curvature of 5.36mm on the front surface.
The 67-448 lens features a standard NIR II coating on both the front and back surfaces, providing improved transmission and reduced reflection in the NIR II range. This coating is part of Edmund Optics' NIR-II coating family, which is designed to enhance performance in the NIR spectrum.
Please note that the lens has a circular base shape and the provided data is for a single lens. For more information, including pricing and availability, please refer to the vendor's website using the provided weblink.
