The ideal first stereo microscope is the Celestron Labs S20 Angled Stereo Microscope. This 20x low-power stereoscope captures a three-dimensional image of your specimen. It's perfect for observing things like pebbles, coins, stamps, insects, and more. The ergonomically inclined head of the microscope lessens neck strain for more pleasant viewing times. You can alter the lighting and background for any subject with the help of upper and lower LED illumination and adjustable stage plates. Users' interpupillary distances are taken into account when adjusting the binocular eyepieces. After positioning the eyepieces as desired, fine-tune focus using the rack-and-pinion focus knob. Use the provided stage clips to hold the reservoir slide in place while inspecting pond water. The microscope is portable and lightweight. It can be used in a lab, on a desk, or in the field because it is battery-operated. Both students and enthusiasts can use it effectively. Accessories Included Your Celestron Labs S20 comes complete with two insects in clear resin, two stage plates, and a dust cover. The insects are ready to observe right out of the package. The two stage plates come in frosted white and reversible black/white. Protect your instrument with the dust cover when it is not in use.
