38-398-INK 12.5mm Dia. x 15mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 38-398-INK is a Plano-Convex lens with a diameter of 12.5mm and a focal length of 15mm, sourced from the renowned optical component vendor, Edmund Optics. This lens is specifically designed for use in the Near-Infrared II (NIR II) spectrum, with a wavelength of 587.6nm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties, including a high Abbe number and low dispersion. This makes it an ideal choice for applications that require high image quality and minimal chromatic aberration.
The 38-398-INK features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II coating. This coating is designed to enhance the lens' performance in the NIR II spectrum, improving transmission and reducing reflection.
The lens geometry includes an inner radius of 0mm and an outer radius of 0mm, with a thickness at the edge of 1.19mm and a thickness at the center of 1.9mm. The back focal length is 48.75mm, and the effective focal length is 50mm.
