67-461-INK 6.0mm Dia. x 9.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-461-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 6.0mm and a thickness of 0.95mm at the edge, with a center thickness of 1.75mm. The effective focal length (EFL) of this lens is 9mm, making it suitable for a variety of optical applications.
The lens is made from n-sf5 Schott, a high-quality optical material known for its excellent transmission properties in the near-infrared (NIR) range. The front and back surfaces of the lens are coated with the EDM NIR-II standard curve coating, which is specifically designed for use in the NIR II range of 750-1550nm. This coating enhances the lens's performance in the NIR II range, making it an ideal choice for applications that require high-quality imaging in this spectral region.
The lens is inked, a process that involves applying a dye to the edge of the lens. This is often done for identification or tracking purposes. The ink does not affect the optical performance of the lens.
