Very Good for the Price,
Verified Purchase(What's this?)
This review is from: AmScope M100C-LED 40x-1000x All-Metal Student Cordless LED Field Biological Compound Microscope with All Optical Glass Lenses (Misc.)
I ordered the "AmScope 40x-1000x All-Metal Student Cordless LED Field Biological Compound Microscope with All Optical Glass Lenses" to teach my daughter about science. The microscope arrived properly packaged and in good condition. This is the SX-BL unit based on the documentation that came with the unit. The images included in the product description give a good idea of how items will appear in the microscope when it is used properly. The unit itself is lightweight but capable. Some notes:
There is no fine control knob. This can make focusing at high magnifications tricky. Use very small increments, and focus at lower magnifications first.
There is no explanation for the use of the condenser aperture (The rotating plastic disk with the various sized holes in it attached to the underside of the stage) in the instructions.
The eyepiece is easily replaced with the aid of a 2mm #0 Phillips head screwdriver. I got mine at Radio Shack. There is a small brass set screw on the barrel of the microscope that holds the eyepiece in place. Back the screw out until the eyepiece comes free when swapping the 10X and 25X eyepieces. Combined with the 4X, 10X and 40X objectives that gives 40X-100X-250X-400X-1000X magnification steps. I will have to double check, but believe these are standard DIN objectives.
All in all a solid piece of equipment for a VERY reasonable price.
