67-597 5mm Dia. x 10mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
The 67-597 is a high-performance double-convex lens, designed for use in the near-infrared spectrum, specifically between 750 and 1550nm. This lens is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for immediate purchase.
The lens features a 5mm diameter and a 10mm focal length, making it a compact yet powerful option for a variety of applications. The base shape is circular, and the lens is coated with Edmund Optics' NIR-II standard curve on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared spectrum, ensuring optimal light transmission and image quality.
The geometry of the lens includes a 1.36mm edge thickness and a 2mm center thickness. The effective focal length (EFL) is 10mm, and the radii of curvature are 9.98mm for the first surface and -9.98mm for the second surface. The back focal length (BFL) is 9.31mm, and both the inner and outer radii are 0mm.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This makes the 67-597 an ideal choice for applications that require high-resolution imaging and precise light control, such as biomedical research, hyperspectral imaging, and night vision technology.
