67-512-INK 12.7mm Dia. x 38.1mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-512-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 1.72mm at the edge, increasing to 3mm at the center. The effective focal length (EFL) of this lens is 31.8mm, 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) spectrum, which covers the wavelength range of 750-1550nm. This coating enhances the lens's performance in the NIR II spectrum, making it ideal for applications such as biomedical imaging, night vision, and spectral analysis.
The lens is inked, a process that adds a dye to the lens to make it easier to handle and identify. This feature is particularly useful in large-scale production environments where misidentification of lenses can lead to costly errors.
