The problem is that the stage is heavy and the adjustment screws are loose. You need to tighten the coarse adjustment knob screws in order to create more friction so that the stage stays put. That, or don't adjust anything and keep holding on to the coarse adjustment while you're using it.

You can remove pieces from the stage like the condenser lense if you don't have the right tools for adjusting the screws

Good afternoon. I bought a Deluxe Digital


Hello, Have you tried putting something under the microscope and then trying to focus on it?Maybe the lens is out of focus. See if there's nothing obstructing the lens. If problem persists after trying those two things you should probably send it to warranty as there most likely is a bad connection between the lcd and the camera.
Hope you can fix it easily.Best regards Vlad

After focusing it drifts out of focus. The knobs do not stay in the same place


There is a tension adjustment just inside the coarse focus knob. (same side as the switch) It looks like a chrome ring with 2 or 3 holes in it. You may have an odd looking tool that came with your microscope that is used to make this adjustment. Tighten it just a bit until the stage stops falling. You don't want it too tight or it will begin to make it difficult to adjust your coarse focus.

The small knob that moves the slideto the left or right on the platform (the one furthest from the observer) is slightly loose, and instead of rotating in a smooth circular motion it rotates rather...


The knob you are talking about is called the x-axis control knob. It does not directly affect the focus. What affects the focus is the slight manipulation of the stage and or slide while you are adjusting the x-axis control knob. It only takes the slightest pressure to throw the focus off very far. Theoretically you could completely remove the specimen holder and move the slide around with your fingers.
The specimen holder may need to be replaced but without further more detailed knowledge of the mechanical problem I cannot instruct further.

My premiere microscope MS-01 Ultra will not focus


There is what is called a "stage stop" screw. Its purpose is to limit the specimen from rising high enough to contact the objective lens. The "stage stop" screw is directly behind the black stage platform in plain sight and very easy to access. It is a thumb screw and sits vertically. Simply loosen it a bit to allow the specimen to rise high enough to focus.

Stage slides down after focusing


There is a tension adjustment for this. It is located on the coarse focus knob which is on the same side as the switch. It looks like a chrome ring with about 3 holes in it. A strange looking tool should have come with the scope. It is designed to fit into these holes and allow you to adjust the tension on the coarse focus knob. You need to tighten it just a little bit. Not too much or you will have trouble operating the coarse focus knobs smoothly.

My microscope won't focus, i tried everything...i don't know what is wrong with it...it's brand new.. it worked a couple times but now it just stopped.. i dont know what brand it is...all it says is...


If your stage is still in its correct orientation then make sure your objective lenses are screwed in tight as well as the eye piece being secured correctly. Try using different objectives (don't go too high or you may damage your lenses if you ram it into your specimen) and using the fine and course focus. If the you still cant focus using different objectives it's quite possible that your mirrors or lenses inside the microscope have been knocked loose. I would then recommend only having it repaired by a certified microscope technician. If it is still under warranty take it back to the store of purchase or send it back to the manufacturer.
