48-738 12.0mm Dia. x 42.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 48-738 is a Plano-Convex Spherical Lens, sourced from Edmund Optics, offering a 12.0mm diameter and a focal length of 42.0mm. This lens is designed for use within the near-infrared (NIR) spectrum, specifically between 600-1050nm, making it suitable for a range of applications within this wavelength range.
The lens is fabricated from N-BK7 Schott glass, a popular choice due to its excellent optical properties and versatility. The Plano-Convex geometry, where one side is flat and the other curved, allows for efficient light collection and focusing. The lens has a central thickness of 2.7mm and an edge thickness of 1.85mm, providing a robust structure while maintaining a sleek profile.
The lens features a standard EDM NIR-I coating on both the front and back surfaces. This coating enhances the lens' performance within the NIR spectrum by reducing surface reflections and improving transmission. The coating is designed to the standard EDM NIR-I curve, ensuring consistent performance across similar products.
