AmScope - 3.5X-180X Simul-Focal Trinocular Boom Stereo Microscope with LED Fiber Optics + 18MP USB 3.0 Camera - SM-4TPZZ-30WR-18M3

3.5X-180X extended zoom magnification using high-quality Greenough stereoscopic objective lenses with 10X and 20X eyepieces, and 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. A 30W LED illuminator with 35" heavy-duty fiber-optic ring-light provides the smoothest overhead lighting possible. The cool, energy-efficient light-source with active cooling prevents excessive heat.
