45-479 9.0mm Dia. x 36.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
This is a 9.0mm diameter, 36.0mm focal length Plano-Convex lens, specifically designed for the visible to near-infrared spectrum (VIS-NIR), covering the wavelength range of 400-1000nm. The lens is sourced from the renowned optical vendor, Edmund Optics.
The lens is made of the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including a low refractive index and low dispersion. This makes the lens suitable for a wide range of applications, particularly where high image quality and color correction are essential.
The Plano-Convex geometry of the lens, where one side is flat and the other is curved, provides a large, flat surface for easy integration into optical systems. The lens has a center thickness of 2.3mm and an edge thickness of 1.75mm, providing a robust and durable design.
The lens features a VIS-NIR coating on both the front and back surfaces, denoted as 'edm visnir0sp2002000'. This coating is designed to enhance the lens's performance in the VIS-NIR spectrum, reducing surface reflections and improving transmission. The coating also provides protection against environmental factors, ensuring the longevity and reliability of the lens.
