The 63-626 is a high-quality double-convex lens, sourced from the renowned optical vendor, Edmund Optics. This lens is designed for use in the near-infrared (NIR) spectrum, specifically for wavelengths between 600 and 1050nm.
The lens features a 5mm diameter and a focal length of 5mm, making it a compact yet powerful option for various optical applications. The double-convex geometry, characterized by its two convex surfaces, provides a wide field of view and low distortion, making it suitable for imaging and other applications where a large, undistorted image is required.
The lens is constructed from n-SF5 Schott, a high-index material that allows for superior optical performance. The front and back surfaces of the lens are coated with Edmund Optics' standard NIR-I coating, which enhances transmission in the NIR spectrum and provides excellent environmental resistance.
The lens has a thickness of 1.44mm at the edge and 2.5mm at the center, providing robustness and durability. The inner and outer radii are 0mm, indicating a uniform curvature across the lens surface. The back focal length (BFL) is 4.19mm, which is crucial for determining the position of the lens in an optical system.
