67-520 15.0mm Dia. x 40.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 15.0mm diameter by 40.0mm 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-SF5 Schott, a material known for its excellent optical properties in the NIR range.
The lens features a standard curvature coating on both the front and back surfaces, specifically the EDM NIR-II STD curve. This coating is designed to enhance the lens' performance in the NIR II region, which spans from 750nm to 1550nm.
The lens has a center thickness of 3.35mm and an edge thickness of 1.36mm. The effective focal length (EFL) is 22.5mm, and the back focal length (BFL) is 20.5mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature.
This lens is a spherical lens, meaning it has a spherical surface. The radius of curvature (R1) of the curved surface is 15.12mm. The base shape is circular, making it suitable for a wide range of applications.
