67-486 10.0mm Dia. x 20.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

The 67-486 is a Plano-Convex lens with a diameter of 10.0mm and a focal length of 20.0mm, sourced from the renowned optical components vendor, Edmund Optics. This lens is specifically designed for use in the Near-Infrared (NIR) spectrum, covering the wavelength range of 750-1550nm, making it ideal for a wide range of applications in this spectral region.

The lens is made from n-sf11 Schott, a high-index glass with excellent optical properties in the NIR range. The Plano-Convex geometry, where one side is flat and the other is curved, is a common design for lenses used in imaging systems. This particular lens has a curvature radius (R1) of 7.85mm and a back focal length (BFL) of 8.18mm.

The 67-486 lens features a standard NIR II coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the NIR range by reducing reflections and increasing transmission. The coating curve is also specified as 'edm nir-ii std curve', which is a standard coating curve provided by Edmund Optics for their NIR II coated lenses.

The lens has a thickness of 1.45mm at the edge and 3.25mm at the center. The inner and outer radii are both 0mm, indicating that the lens is a simple Plano-Convex design without any additional features like threads or mounts.
