67-602 6mm Dia. x 9mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
This is a 6mm diameter by 9mm focal length (FL) double-convex lens, specifically designed for use in the near-infrared (NIR) spectrum, covering the wavelength range of 750-1550nm. The lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock.
The lens is made from the high-quality material, n-BK7 Schott, which is renowned for its excellent optical properties. The lens features a double-convex geometry, with a radius of curvature of 8.91mm for both the front and back surfaces. This shape provides a broad field of view and low distortion, making it ideal for a wide range of applications.
The lens has a center thickness of 2.25mm and an edge thickness of 1.22mm, providing robustness and durability. The effective focal length (EFL) is 9mm, which, combined with the 6mm diameter, makes this lens suitable for use in compact optical systems.
The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the NIR spectrum, reducing reflection and increasing transmission. The coating is specified to the standard curve, ensuring consistent performance across different lenses.
