This lightweight, multi-zone ring light for stereo microscopes provides a smooth ring of bright, white illumination. 80 low-heat LEDs create a seamless light-source to virtually eliminate shadows, making this ideal for both biological and industrial applications. Mounted to the microscope's objective housing, the light never needs to be repositioned, so it's always where it's needed. This multi-zone model uses touch-sensitive controls to independently enable or disable 4 quadrants for customized lighting. You can use the full 360° ring or any combination of zones to produce more direct lighting. This ring-light is compatible with various stereo microscopes including our SM, SW, and ZM series. A 48mm threaded mounting adapter is included.
