67-615 10mm Dia. x 15mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
The 67-615 is a high-performance double-convex lens, designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. This lens is sourced from Edmund Optics, a leading manufacturer of optical components.
The lens boasts a 10mm diameter and a 15mm focal length, making it a versatile choice for a range of applications. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 14.88mm on both the front and back surfaces. This design results in an effective focal length (EFL) of 15mm and a back focal length (BFL) of 13.8mm.
The lens is constructed from N-BK7 Schott glass, a popular material for optical components due to its excellent optical properties and high transmittance in the visible and NIR spectra. The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces, enhancing its performance in the NIR range.
The coating is designed to provide high transmission and low reflectance, making the lens ideal for use in applications such as night vision, thermal imaging, and spectral analysis. The lens is currently in stock and available for immediate shipping, as indicated by its valid web link status.
