63-635 10mm Dia. x 30mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm

The 63-635 is a high-quality double-convex lens, 10mm in diameter and 30mm in focal length, sourced from the renowned optical components vendor, Edmund Optics. This lens is designed for use within the near-infrared (NIR) spectrum, specifically between 600 and 1050 nanometers, making it suitable for a wide range of applications within this wavelength range.

The lens is constructed from N-BK7 Schott glass, a popular material in optical systems due to its excellent optical properties and versatility. The double-convex shape, characterized by two outwardly curved surfaces, is designed to focus light onto a single point, making this lens ideal for imaging and focusing applications.

The 63-635 features a standard coating of EDM NIR-I on both the front and back surfaces. This coating is specifically designed to enhance performance within the NIR spectrum, reducing reflection and increasing transmission. The coating also provides excellent environmental stability, ensuring the lens maintains its performance over time.

The lens has a center thickness of 2.5mm and an edge thickness of 1.68mm, providing a robust and durable design. The inner and outer radii are 0mm, indicating a symmetrical curvature. The effective focal length (EFL) is 30mm, and the back focal length (BFL) is 29.17mm.
