67-565-INK 25.4mm Dia. x 88.9mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-565-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 25.4mm and a thickness of 1.72mm at the edge, with a center thickness of 5mm. The effective focal length (EFL) of this lens is 50.8mm, making it suitable for a variety 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 coating specifically 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 adds a dye to the lens during manufacturing. This can be used for a variety of purposes, such as marking the lens for identification or enhancing contrast in certain applications.
Please note that the lens is spherical, meaning it has a curved surface. The radius of curvature for the first surface (R1) is 26.25mm, and the back focal length (BFL) is 47.5mm. The lens does not have an inner or outer radius, as it is a simple Plano-Convex design.
