67-545 25.0mm Dia. x 40.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, with a diameter of 25.0mm and a focal length of 40.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically catering to the wavelength range of 750-1550nm.

The lens is made from n-SF5 Schott, a material known for its excellent optical properties, making it suitable for a wide range of applications. The lens features a front and back coating of edm nir-ii std curve, which enhances its performance in the NIR II spectrum.

The geometry of the lens includes an edge thickness of 2.43mm and a center thickness of 8mm. The lens's effective focal length (EFL) is 25mm, and the radius of curvature (R1) is 16.82mm. The back focal length (BFL) is 20.22mm, and both the inner and outer radii are 0mm.

This lens is a Spherical Lens, which means it has a surface that is a portion of a sphere. The lens's base shape is circular, making it compatible with various optical systems. The lens's coating and material ID make it an ideal choice for applications that require high-performance in the NIR II spectrum.
