4.5mm Diameter x 4.5mm FL NIR I Coated Double-Convex Lens for 600-1050nm Wavelength
This 4.5mm Diameter x 4.5mm FL NIR I Coated Double-Convex Lens, sourced from Edmund Optics, is a high-quality optical component designed for use within the near-infrared (NIR) spectrum of 600-1050nm. Its spherical design, with a base shape of a circle, features two convex surfaces (double-convex) that effectively manage light transmission and minimize optical aberrations.
The lens boasts a diameter of 4.5mm and a focal length (FL) of 4.5mm, yielding an f-number of 1. The edge thickness is 1.8mm, while the center thickness is 2.6mm, ensuring robustness and structural integrity. The effective focal length (EFL) is 3.7mm, and the radii of curvature for the first and second surfaces are 6.58mm and -6.58mm, respectively.
The lens material is n-lasf44 schott, which is well-suited for NIR applications. Both the front and back surfaces are coated with the EDM NIR-I STD CURVE coating, enhancing transmission and reducing surface reflections within the NIR spectrum.
This lens is an excellent choice for researchers, engineers, and optical designers seeking a reliable and efficient NIR optical component for their projects. With its high-quality construction, precise specifications, and compatibility with the NIR spectrum, this double-convex lens is sure to meet the demands of a wide range of applications.
