67-564-INK 25.4mm Dia. x 76.2mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm

The 67-564-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 25.4mm and a thickness ranging from 2.36mm at the edge to 7mm at the center. The effective focal length (EFL) of this lens is 38.1mm, making it suitable for a variety of applications.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The front and back surfaces of the lens are coated with EDM NIR-II std curve, a coating specifically designed for use in the Near-Infrared II (NIR II) region, which covers the wavelength range of 750-1550nm. This coating enhances the lens's performance in the NIR II region, making it ideal for applications such as biomedical imaging, night vision, and spectral analysis.

The lens is circular in shape and has an inner radius of 0mm and an outer radius of 0mm. The front surface of the lens has a radius of curvature (R1) of 19.69mm, while the back focal length (BFL) is 33.48mm.

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/.
