67-514-INK 12.7mm Dia. x 50.8mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-514-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 1.3mm at the edge, which increases to 2.3mm at the center. The effective focal length (EFL) of this lens is 40mm, making it suitable for a wide range of optical 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 specialized coating designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. This coating enhances the lens's performance in the NIR range, making it ideal for applications such as night vision, thermal imaging, and spectroscopy.
The lens is inked, a process that typically involves applying a dye or pigment to the lens to enhance contrast or mark it for identification purposes. However, the specific use of ink in this lens is not detailed in the provided data.
