49-468 9mm Dia. x 36mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 49-468 is a high-quality double-convex lens, boasting a 9mm diameter and a focal length of 36mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock. The lens is designed for use within the near-infrared spectrum, specifically between 600 and 1050nm, making it ideal for a wide range of applications in this wavelength range.
The lens is constructed from Schott's n-BK7 glass, a material well-known for its excellent optical properties, including a high Abbe number and low dispersion. This makes the lens particularly suitable for applications requiring high image quality and color correction.
The 49-468 features a standard coating on both the front and back surfaces. This coating, identified as 'edm nir-i std curve', is specifically designed to enhance the lens' performance within the near-infrared spectrum. It aids in reducing surface reflections and increasing transmission, thereby improving the overall efficiency and quality of the optical system in which it is used.
The lens geometry is characterized by its double-convex shape, with radii of curvature of 36.77mm and -36.77mm for the first and second surfaces, respectively. The lens has an edge thickness of 2mm and a center thickness of 2.55mm, providing a robust and durable design. The effective focal length (EFL) is 36mm, and the back focal length (BFL) is 35.15mm.
