38-329 6.0mm Dia. x 20mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
This is a 6.0mm diameter, plano-convex lens with a focal length of 20mm, designed for use in the near-infrared spectrum. The lens is sourced from Edmund Optics and is currently in stock. It is made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion.
The lens features a front and back coating of EDM NIR-I std curve, which is a broadband anti-reflection coating specifically designed for the near-infrared region, enhancing transmission and reducing surface reflections. The edge thickness of the lens is 1.01mm, while the center thickness is 1.45mm, providing a balanced structure for optimal performance.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature. The base shape is circular, ensuring a wide field of view and minimal distortion. The lens's effective focal length (EFL) is 20mm, which, combined with its diameter, provides a decent depth of field and a wide range of applications.
