45-866 9mm Dia. x 9mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-866 is a high-quality double-convex lens, boasting a 9mm diameter and a focal length of 9mm. This lens is sourced from Edmund Optics, a renowned vendor known for their exceptional optical components. The lens is designed for use within the visible to near-infrared spectrum, spanning from 400 to 1000nm, making it a versatile choice for a wide range of optical applications.
The lens is constructed from n-SF5 Schott, a high-performance glass material that offers excellent optical properties. The double-convex shape, characterized by its two convex surfaces, provides a focused beam of light, making it ideal for imaging and other focusing applications. The lens has a center thickness of 3.45mm and an edge thickness of 1.6mm, providing a robust and durable design.
The lens features a VIS-NIR coating on both the front and back surfaces, enhancing its performance within the specified wavelength range. This coating reduces surface reflections, improving transmission and overall image quality. The coating is applied using the EDM VISNIR0SP2002000 process, ensuring a high-quality, consistent application.
