67-449 4.0mm Dia. x 10.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-449 is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens boasts a diameter of 4.0mm and a focal length of 10.0mm, making it a compact yet powerful addition to any optical system.
The lens is crafted from the high-quality material, N-BK7 Schott, a borosilicate glass known for its excellent optical properties, including a low refractive index and low dispersion. This material ensures high-quality image transmission and minimal chromatic aberration.
The 67-449 features a plano-convex geometry, where one side is flat, and the other is curved. The curvature of the lens is defined by a radius of 5.19mm, which contributes to its focusing power. The lens's thickness varies from 1.24mm at the edge to 1.64mm at the center, providing a balanced optical path.
The 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 II region, specifically between 750nm and 1550nm. It ensures high transmission rates and reduces unwanted reflections, contributing to improved system performance.
