40mm Diameter x 60mm FL NIR I Coated Double-Convex Lens for 600-1050nm
This 40mm diameter x 60mm focal length (FL) NIR I coated double-convex lens is a high-quality optical component designed for use in the near-infrared (NIR) spectrum, specifically between 600 and 1050nm. Sourced from the renowned optical vendor, Edmund Optics, this lens is part of our extensive catalog of optical elements.
The lens is constructed from Schott's n-BK7 material, a borosilicate glass known for its excellent optical properties, including a high refractive index and low dispersion. This makes it ideal for a wide range of optical applications, particularly where high image quality and low chromatic aberration are critical.
The lens features a double-convex geometry, with radii of curvature of 60.56mm for both the front and back surfaces. This shape provides a strong focusing power, making it suitable for use in imaging systems, beam shaping, and other applications where a tight focus is required. The lens has an effective focal length (EFL) of 60mm, providing a moderate magnification and field of view.
The lens is coated with Edmund Optics' NIR I standard curve coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the NIR spectrum, improving transmission and reducing reflection. The coating status is valid and in stock, ensuring quick and reliable delivery.
