AmScope 144 LED Quadrant Ring Light For Stereo Microscopes, ø61mm ID, 12VDC Ring Light

AmScope 144 LED Quadrant Ring Light for Stereo Microscopes is a four-zone, intensity-adjustable top illumination accessory that mounts around the objective with a 61 mm (2.4 in) inner diameter. The 144 LEDs are arranged in four independent quadrants, enabling selective lighting from multiple directions to reduce glare and sculpt shadows for enhanced detail across a range of specimens. Designed for stereo microscopes, it provides a bright, uniform field at common working distances, with brightness adjustable to suit both low-contrast and reflective surfaces. Powered by a 12 V DC supply, this ring light is part of AmScope’s LED-144 family of modular illumination options, all sharing the same 61 mm mounting size and four-zone concept. The compact ring keeps illumination centered on the region of interest while integrating with standard 61 mm ring mounts used on many microscope heads, making it a straightforward upgrade for improved imaging fidelity in tasks such as material inspection, microelectronics, and biology sample work.
