The Mantis seems a bit pricey, first the LED is not long lasting and the objectives are sold separately. The Compact Mantis costs $2574.98 at All Spec Company. This will not include the objectives. The price for a popular 4X is $121.88 and 6X is $210.94. The magnification is maximum at 10X and lower. The resolution is lower, but the depth of field and wide field of view, low N.A., numerical aperture, but the benefit is eyepieceless, ocularless, thus great for soldering and parts ID. This is basically the ultimate hand lens, which a hand lens on a good neck or articulated arm does the same function for less than $100.00 in the 2X, 4X, and 6X. The Mantis is special in the 10X. It is not for the hobbyist, more for an industrial factory. Your 1970s Olympus SZ greenough principle stereo microscope has more resolution and magnification, but less working distance and depth of field and need to look though an ocular. You can place a digital camera or video camera on the eyepiece and view through a larger panel LCD or LED screen. I am currently working on a Nikon Coolscope, but that is a compound for slides robot drone microscope with a broken power supply. Thanks for posting the video, totally fun to view you set one up and use one.
