This 4.5mm Dia. x 9.0mm FL NIR I Coated Plano-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 plano-convex base shape and circular geometry, ensures excellent light transmission and focus.
The lens boasts a 4.5mm diameter and a 9.0mm focal length, yielding an f-number of 2.0. The edge thickness is 1.8mm, while the center thickness is 2.38mm, providing consistent performance across the lens. The lens's effective focal length (EFL) is 9mm, and its front and back radii are 4.65mm and 7.41mm, respectively.
The lens is crafted from the renowned N-BK7 glass from Schott, a material known for its excellent optical properties and versatility. The lens features EDM NIR-I standard curve coatings on both the front and back surfaces, enhancing transmission within the NIR range and reducing surface reflections.
This Plano-Convex Lens is an ideal choice for applications requiring a compact, high-performance optical component within the NIR spectrum. Its compatibility with various wavelengths and coatings makes it a versatile solution for numerous industries, including biomedical, industrial, and scientific research.
