38-412 12.7mm Dia. x 100.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

The 38-412 is a Plano-Convex lens with a diameter of 12.7mm and a focal length of 100.0mm, sourced from the renowned optical components vendor, Edmund Optics. This lens is specifically designed for use in the Near-Infrared II (NIR II) spectrum, covering a wavelength range of 750-1550nm, making it ideal for applications such as biomedical imaging, night vision, and spectral analysis.

The lens is crafted from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The Plano-Convex geometry, with a center thickness of 1.6mm and an edge thickness of 1.22mm, ensures efficient light transmission and minimal distortion. The lens's front and back surfaces are coated with Edmund Optics' standard NIR-II coating, further enhancing its performance in the NIR II spectrum by reducing surface reflections and increasing transmission.

The item data also provides additional geometric details, such as the inner and outer radii, which are both 0mm, indicating a flat inner surface and a curved outer surface. The first radius of curvature (R1) is 51.68mm, and the back focal length (BFL) is 98.95mm. These specifications, along with the effective focal length (EFL) of 100mm, allow for precise integration into optical systems.
