48-272 50mm Dia. x -125 FL; VIS 0deg Coated; Plano-Concave Lens 425-675nm
The 48-272 is a Plano-Concave Spherical Lens with a 50mm diameter, manufactured by Edmund Optics. This lens is designed for use within the wavelength range of 425-675nm, making it suitable for a variety of applications within the visible light spectrum.
The lens features a base shape of a circle, with a thickness of 9.87mm at the edge and 5mm at the center. The effective focal length (EFL) is -125mm, and the back focal length (BFL) is -128.3mm. The inner and outer radii are both 0mm, indicating a uniform curvature.
The lens is made from N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and high Abbe number. This makes the lens suitable for use in high-precision applications where chromatic aberration needs to be minimized.
The lens is coated with the EDM VIS-0 STD CURVE coating on both the front and back surfaces. This coating is designed to provide high transmission across the visible spectrum, enhancing the overall performance of the lens.
