This high quality 3.5X-90X trinocular stereo zoom microscope comes with SUPER widefield optics and a track stand with dual LED illuminators. It has been designed for use in organic or temperature-sensitive applications - like dissecting live tissues or observing live organisms. Our low-temperature LED system allows you to use both incident illumination which shines light down onto a 3-dimensional specimen and reflecting-plate bottom illumination which shines light up through a transparent sample. Because the top and bottom LED lights are controlled by separate dimmers you are able to customize lighting for the optimal level of illumination whatever the situation. The optics of this SM series microscope features a large zoom magnification range which produces sharp crystal-clear stereo images while providing a generous working distance. The 360 degree swiveling trinocular head is attached at a 45 degree angle which ensures easy and comfortable observation - especially when used in conjunction with the included rubber eye-guards. On the base the LED reflecting-plate measures 3-3/4 or 95 mm in diameter. This microscope is especially useful for applications that require cool illumination. It is perfect for the examination of organic matter such as insects plants or virtually any 3-dimensional temperature-sensitive object. It is ideal for those who work in biology forestry archaeology and agriculture. With its high resolution good depth and broad field of view this microscope can be used for both educational and professional purposes in research labs hospitals schools and veterinary offices. This microscope provides all the excellent features of a high quality laboratory instrument at an affordable price.
