67-447 4.0mm Dia. x 6.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 4.0mm diameter by 6.0mm focal length plano-convex lens, specifically designed for use in the near-infrared (NIR) spectrum. The lens is sourced from Edmund Optics and is currently in stock. It is made from N-BK7 Schott glass, a popular material for its high refractive index and low dispersion.
The lens features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II coating. This coating is designed to enhance the lens' performance in the NIR II range, which spans from 750nm to 1550nm.
The lens has a center thickness of 2.26mm and an edge thickness of 1.53mm. The front surface has a radius of curvature of 3.11mm, resulting in a back focal length of 4.51mm. The effective focal length of the lens is 6mm. The lens does not have any inner or outer radii, indicating a simple, plano-convex geometry.
