67-423 1.0mm Dia. x 0.6mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-423 is a 1.0mm diameter, 0.6mm focal length plano-convex lens, specifically designed for use in the near-infrared (NIR) spectrum, covering the wavelength range of 750-1550nm. This lens is sourced from Edmund Optics, a leading provider of optical components.
The lens is made from n-lasf9 Schott, a material known for its excellent optical properties in the NIR range. The plano-convex geometry, with a 0.51mm radius of curvature, provides a 0.17mm back focal length, making it suitable for a wide range of applications. The lens has a center thickness of 0.8mm and an edge thickness of 0.39mm, ensuring robustness and durability.
The lens features a standard NIR II coating on both the front and back surfaces, providing excellent transmission and reducing reflections in the NIR range. This coating is part of Edmund Optics' NIR-II series, known for its high performance and reliability.
