86-925 75.0mm Dia. x 500.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 86-925 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a large 75.0mm diameter and a focal length of 500.0mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a standard NIR II coating on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared spectrum, specifically between 750nm and 1550nm, by reducing reflection and increasing transmission. The front surface of the lens has an edm nir-ii std curve coating, while the back surface has an edm nir-ii std curve coating, both designed to optimize its performance in the NIR II range.
The lens has a thickness of 3.79mm at the edge and 5mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 500mm, and the back focal length (BFL) is 496.7mm. The radius of curvature (R1) of the lens is 258.4mm.
