This is a first-class 7X-45X trinocular stereo zoom microscope with LED cool illumination system. Designed to meet the demands of the modern microscopy applications that are temperature-sensitive like dissecting live tissues or observing live creatures this scope exceeds all expectations. It incorporates all the most excellent features of a high quality laboratory instrument. This microscope comes with SUPER widefield optics and versatile LED illumination system that provides both incident (top) cool lighting and transmitted (bottom) cool illumination. You can choose between incident illumination shining down onto the object or transmitted illumination through the frosted stage plate. The first is used for the observation of three-dimensional objects and the second for the inspection of the objects that allow light to get through them. This microscope offers high resolution and good depth within a broad field of view. It provides crystal clear sharp stereo images wide zoom magnification range and large working distance. Its 45 degree inclined 360 degree swiveling trinocular head ensures an easy observation and rubber eyeguards provide further comfort. This microscope is especially useful for the applications that need cool illumination. It can be used in biology forestry archaeology and agriculture. It is appropriate for educational purposes in hospitals and schools. It is perfect for the examination of insects plants or virtually any three dimensional temperature-sensitive objects.
