SLB-50-80NIR1 50.0 mm Dia. x -80.0 mm FL; Coated; Plano-Concave Lens 633-1064nm
The SLB-50-80NIR1 is a Plano-Concave Spherical Lens, 50.0 mm in diameter with a focal length of -80.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The lens features a concave shape on one side and a flat surface on the other, with a thickness of 11.4 mm at the edge and 3 mm at the center. The inner and outer radii are both 0, indicating a uniform curvature. The effective focal length (EFL) is -80 mm, and the back focal length (BFL) is -82 mm.
The SLB-50-80NIR1 is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the 633-1064nm wavelength range. This coating is specifically designed to optimize the lens's performance in the near-infrared spectrum, making it ideal for applications such as laser systems, spectroscopy, and imaging.
