67-592 3mm Dia. x 6mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
The 67-592 is a high-quality double-convex lens, designed and manufactured by Edmund Optics, a leading global provider of optical components. This lens boasts a 3mm diameter and a focal length of 6mm, making it a compact yet powerful addition to any optical system.
The lens is crafted from n-BK7 Schott, a renowned optical glass known for its excellent transparency and low dispersion. This material ensures that the lens delivers sharp, clear images across a wide spectrum of wavelengths, from 750nm to 1550nm, a range that falls within the Near-Infrared II (NIR II) spectrum.
The 67-592 lens features a standard curve coating on both the front and back surfaces, specifically Edmund Optics' NIR-II coating. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving the overall efficiency and quality of the optical system.
The lens's geometry is meticulously designed, with an inner radius of 0mm and an outer radius of 0mm. The center thickness is 1.8mm, while the edge thickness is 1.41mm, providing a robust and durable structure. The lens's effective focal length (EFL) is 6mm, and the back focal length (BFL) is 5.37mm, offering flexibility in system design.
