67-511-INK 12.7mm Dia. x 31.8mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-511-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a circular base shape with a diameter of 12.7mm and a thickness of 1.34mm at the edge, increasing to 2.7mm at the center. The effective focal length (EFL) is 30mm, and the lens's front surface has a radius of curvature of 15.51mm. The back focal length (BFL) measures 28.22mm.
This 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 NIR-II coating on both the front and back surfaces, designed to enhance performance in the near-infrared spectrum, specifically between 750nm and 1550nm. This makes the lens ideal for applications such as night vision, thermal imaging, and spectroscopy.
The lens is inked, a process often used to mark lenses with important information such as part numbers, making identification and tracking easier. Please note that the ink may affect the lens's performance in specific applications, so it's crucial to consider this factor when making your selection.
