84-383 3mm Dia. x -6 FL; NIR I Coated; Plano-Concave Lens 600-1050nm
The 84-383 is a 3mm diameter Plano-Concave Spherical Lens with a -6 FL (focal length) and a -4.71 radius of curvature (RoC) on the front surface and a -6.56 back focal length (BFL). This lens is sourced from Edmund Optics and is available in stock.
The lens is made of n-sf11 Schott material, which is known for its high refractive index and low dispersion, making it ideal for applications that require excellent image quality and color correction. The lens has a center thickness of 1mm and an edge thickness of 1.17mm, providing structural integrity and resistance to deformation.
The 84-383 is coated with EDM NIR-I std curve on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared (NIR) spectrum, specifically between 600-1050nm, by reducing surface reflections and increasing transmission. This makes the lens suitable for applications such as NIR spectroscopy, thermal imaging, and night vision.
