Dino-Lite USB Digital Microscope AM4113ZT – 1.3MP, 10x – 50x, 220x Optical Magnification, Measurement, Polarized Light

Like the other reviewer, we also bought this for inspecting PCB assemblies (or, rather, specific components on them). We have a need to inspect the sides of components, which means looking at the board surface at an extreme oblique angle. For this application, the cap (which is designed to automatically place a plane parallel to the objective lens at the correct focal depth at 200x zoom) got in the way and prevented using much more than about 40x magnification.

Now, I cut this cap off and we can take photos of mounted components from an end-on view at maximum magnification. That being said, if this sounds like your application, I would look at the models which feature a removable cap so you don’t find yourself permanently modifying your new digital microscope.
