The Aven 26800B-303-OLD DSZ-44 Stereo Zoom Binocular Microscope comes with a Double Arm Boom Stand and Fiber Optic LED. This inspection and laboratory microscope system features premium quality optics, design and manufacturing, as well as a uni-body construction and multi-coated optical components for excellent contrast and edge-to-edge definition of 3D images. A 60-LED ring light with dimmer control is built into the focus mount, which has coarse and fine focusing for precise control. This energy-saving, productivity enhancing feature ensures color consistency when dimming, and a flicker free experience for operators. The adjustable zoom knob helps to further enhance the precision work experience. The graduations on the zoom knob tell operators the exact magnifications at which they are working. For applications requiring very specific adjustments, this is a particularly convenient feature. These benefits make this system well-suited for high-volume inspection stations, R&D engineering labs, medical or scientific research and education applications. The compact stand in this configuration is ideal for observing small objects and for work areas with limited space. The included Fiber Optic LED provides bright, shadow-free illumination.
