67-508-INK 12.7mm Dia. x 15.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex Lens, specifically designed for use in the Near-Infrared II (NIR II) spectrum, with a diameter of 12.7mm and a focal length of 20mm. The lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens features a spherical shape, with a front radius of curvature of 10.34mm and a back focal length of 17.69mm. The edge thickness of the lens is 1.4mm, while the center thickness is 3.5mm, providing a robust structure.
The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating is specifically designed for use in the NIR II spectrum, providing optimal performance in the 750-1550nm range. The lens is also inked, which is a common practice to mark the orientation of the lens.
