48-704 4.0mm Dia. x 8.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 48-704 is a Plano-Convex lens, a type of spherical lens, with a diameter of 4mm and a focal length of 8mm. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry. The lens is made from the material n-Baf10 Schott, which is known for its high refractive index and low dispersion.
The lens features a front and back coating of EDM NIR-I std curve, which is designed to enhance its performance in the near-infrared spectrum, specifically between 600-1050nm. This coating aids in reducing surface reflections and increasing transmission, making it ideal for applications that require high-quality imaging in the NIR range.
The lens has a thickness of 1mm at the edge and 1.39mm at the center, providing a balanced profile for efficient light transmission. The inner and outer radii are 0, indicating a uniform curvature throughout the lens. The effective focal length (EFL) is 8mm, and the back focal length (BFL) is 7.17mm, which are crucial specifications for designing optical systems.
