38-410 12.7mm Dia. x 30.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 38-410 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens has a circular base shape with a diameter of 12.7mm and a thickness of 1.36mm at the edge, increasing to 3mm at the center. The effective focal length (EFL) of this lens is 25.4mm, making it suitable for a wide range of optical applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmission in the visible and near-infrared regions, making it ideal for applications in this spectral range.
The lens features a NIR II coating on both the front and back surfaces. This coating, part of Edmund Optics' standard curve, is specifically designed for use in the near-infrared region, enhancing transmission and reducing reflection in this spectral range. The coating is particularly effective between 750nm and 1550nm, making this lens an excellent choice for near-infrared optical systems.
The lens's geometry is spherical, with a radius of curvature of 13.13mm on the convex side. The back focal length (BFL) is 23.43mm. The lens does not have any inner or outer radii, indicating a simple, straightforward design.
