I have a mantis that I used for engraving, but I bought a Ziess which I now use all the time. The Mantis has many good features including accommodating any eyeglasses.
Thank you for the video link. The concept of a single optic is indeed very interesting. However I don't know how it would translate in the real world engraving. still More confused than ever.

I have a Mantis.....the concept is great but they just don't work for engraving....the Mantis is sold a inspection microscope and no doubt work well on circut boards or other flat objects where the height and magnification remain the same all the time....the Mantis does not have rack and pinion height adjustment for focusing for a object that is being moved around under the scope....Mantis has a spring loaded height adjustment in the mouting arm which does not work well for engraving....the Mantis is not a stereo microscope and it is difficult to judge the depth of a cut....the Mantis is limited to a fixed lense magnification and cannot be zoomed like a standard microscope....I got the Mantis from a jeweler couldn't make it work for him and he had put it in a corner.... basically I'm like him....Its here but all it's doing is gathering dust....
