Request InfoVolpi USAA high-intensity dark-field LED ringlight, available with red or white surface-mount-device LEDs, has been announced by Volpi USA. It provides intense, shadow-free and homogeneous illumination. As the contrast with the part increases, defects appear bright while the surface of the part remains dark. The ringlight offers improved light output, increased life expectancy and a greater working distance than previous models. Working distance ranges from 20 to 50 mm, and the diameter of the illuminated area, from 58 to 73 mm, depending upon the working distance.See full productRelated content from Photonics MediaWEBINARSPhotonics.com 10/27/2021Fiber Optic Solutions for Medical DevicesSteve Allen provides a brief overview and examples of procedures that continue to push adoption and proliferation of optical fiber-based medical devices.
