38-411 12.7mm Dia. x 40.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 38-411 is a Plano-Convex lens with a diameter of 12.7mm and a focal length of 40.0mm, specifically designed for use in the Near-Infrared II (NIR II) spectrum, which spans from 750 to 1550nm. This lens is sourced from the reputable vendor, Edmund Optics.
The lens is made from the high-quality material n-BK7 Schott, a borosilicate glass known for its excellent optical properties and durability. The lens features a spherical shape, with a front radius of curvature of 19.69mm and a back focal length of 36.12mm. The edge thickness of the lens is 1.95mm, while the center thickness is 3mm, providing a balanced structure for efficient light transmission.
The 38-411 lens is coated with the EDM NIR-II Standard Curve on both the front and back surfaces. This coating enhances the lens's performance in the NIR II spectrum, ensuring high transmission rates and minimal reflectance. The lens's effective focal length (EFL) is 38.1mm, making it suitable for a wide range of optical applications.
