38-420 18.0mm Dia. x 50.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex Lens, sourced from Edmund Optics, designed for use in the Near-Infrared (NIR) spectrum, specifically for wavelengths between 750nm and 1550nm. The lens has a diameter of 18.0mm and a focal length of 50.0mm, making it a versatile option for a variety of applications.
The lens is made from N-BK7 Schott glass, a material well-known for its excellent optical properties and wide transparency range. This makes the lens suitable for use in various NIR applications. The lens features a plano-convex geometry, with a front surface radius of 25.84mm and a back focal length of 48.09mm.
The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the NIR spectrum, reducing reflections and increasing transmission. The coating is a standard curve, ensuring consistent performance across a wide range of applications.
The lens has a thickness of 1.28mm at the edge and 2.9mm at the center. The inner and outer radii are both 0mm, indicating a uniform curvature. This lens is a circular shape, providing a wide field of view and making it suitable for use in imaging systems and other applications where a broad view is required.
