67-501 12.0mm Dia. x 48.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 12.0mm diameter by 48.0mm 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 material, a common choice for its high refractive index and low dispersion.
The lens features a standard NIR-II coating on both the front and back surfaces, which enhances its performance in the 750-1550nm wavelength range. This coating is designed to reduce surface reflections and increase transmission, making it ideal for applications that require high-quality imaging or light transmission in the NIR spectrum.
The lens has a center thickness of 3mm and an edge thickness of 2.01mm. Its effective focal length (EFL) is 36mm, and the radius of curvature (R1) of the convex surface is 18.61mm. The back focal length (BFL) is 34.02mm, and the lens does not have any inner or outer radii.
This lens is a spherical lens, meaning it has a curved surface that is symmetrically rounded. This shape is often used in optical systems because it can focus light to a single point, making it ideal for imaging applications.
