38-368 12.7mm Dia. x 40.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 38-368 is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens boasts a 12.7mm diameter and a focal length of 40.0mm, making it suitable for a wide range of applications.
The lens is crafted from the high-quality material, N-BK7 Schott, a borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This ensures the lens delivers reliable and consistent performance across various temperatures and environments.
The 38-368 features a standard coating of EDM NIR-I on both the front and back surfaces. This coating is specifically designed for the near-infrared spectrum, enhancing transmission within the 600-1050nm range. It also provides protection against environmental factors, ensuring the lens maintains its performance over time.
The lens geometry includes a 1.3mm edge thickness and a 2.3mm center thickness, providing robustness and stability. The inner and outer radii are 0mm, indicating a plano surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 20.67mm, and the back focal length is 38.48mm.
