The compact ring light Leica LED3000 RL uses state-of-the-art LEDs and a specially developed LED attachment lens by Leica. This enhances the uniformity of illumination and increases brightness. By conveniently switchable segments, new information can be obtained from the sample without moving it. The Leica ring light emits light arranged in a ring around the lens onto the sample. Depending on the configuration of the segments, the sample is illuminated from different angles or uniformly illuminated in a ring shape.
