AmScope - 3.5X-90X Trinocular Stereo Microscope, 0.5X and 2X Barlow Lenses, Boom Arm Stand + 144 LED 4 Zone Ring Light - SM-4TZ-144A

3.5X-90X extended zoom magnification using high-quality Greenough stereoscopic objective lenses with 0.5X and 2X Barlow lenses. A highly-versatile stereo microscope on a heavy-duty, multi-pivot boom-stand which allows the microscope to easily swing into place when needed, and away when not. Dual diopters can be adjusted to maintain consistent focus throughout the magnification range, greatly improving productivity. The stereo optics provide upright images with clear depth-of-field and a wide view for hands-on applications and a trinocular photo-port provides a dedicated mount for adding a camera. The 144-LED ring-light uses a power module with four subdivisions to produce either directional light or an encompassing ring of light.
