AmScope 3.5X-90X Binocular Stereo Zoom Microscope with Dual Halogen Reviews

Customer Ratings:

I'm glad I got the model with dual light sources--I think it will be more useful than I expected. There's a switch on the side of the base so you can change from overhead to transmitted light and adjust intensity by feel. There is no separate transformer box as for fiber illumination, just a single power cord. A bit of assembly required, but it was fun and easy. Also in the box are spare bulbs and a cover.

The microscope has good magnification and zoom but the incident light from above isn't positioned very well. It is too high above the lens and when you are zoomed in close it is shadowed by the lens. The lens on the microscope consists of a base objective lens with a 2.5x and a 0.5x extension that are both removeable. The 0.5x extension doesn't really do much because it is so long that it decreases the zoom and field of view to the point that you can't get as close a look at the specimen as you can without it.
