65-308 2.0mm Dia. x 3.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 65-308 is a Plano-Convex Spherical Lens, a type of spherical lens characterized by one side being flat and the other side curved. This particular lens, sourced from Edmund Optics, boasts a diameter of 2.0mm and a focal length of 3.0mm. The lens is made from the material n-lasf9 schott, a detail often crucial for users seeking specific refractive indices or dispersion properties.
The lens's geometry is also noteworthy. It has a thickness of 0.6mm at the edge and 0.8mm at the center, with an effective focal length (EFL) of 3.0mm. The radius of curvature (R1) is 2.55mm, and the back focal length (BFL) is 2.57mm. The lens's inner and outer radii are both 0, indicating a uniform curvature.
The 65-308 is coated with edm nir-i std curve on both the front and back surfaces. This coating is designed to optimize performance within the near-infrared (NIR) spectrum, specifically between 600 and 1050nm. This makes the lens particularly suitable for applications in fields such as biomedical imaging, spectroscopy, and optical telecommunications.
