38-390 9.0mm Dia. x 20mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 38-390 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a 9.0mm diameter and a 20mm focal length, making it suitable for a wide range of applications. The base shape of the lens is circular, and it features a spherical geometry, with a 7.75mm radius on the curved side and a 15mm effective focal length.
The lens is made from N-BK7 Schott glass, a popular material known for its excellent optical properties and versatility. The lens's thickness at the edge is 1.56mm, while the center thickness is 3mm, providing a robust and durable structure. The lens's clear aperture is 9mm, and it has no inner or outer radius, indicating a uniform and consistent optical surface.
The 38-390 lens is coated with Edmund Optics' NIR-II standard curve coating on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared spectrum, specifically between 750nm and 1550nm, making it ideal for applications such as night vision, thermal imaging, and spectral analysis.
