If the coarse adjustment will not go all the way up, the pre-focusing lever may be locked at a too low height. Unlock the pre-focusing lever.
Why does my Olympus BX51 Microscope bulb light intermittently?
If the bulb intermittently lights and goes out, it could be nearly burned out (replace the bulb) or a connector is not properly connected (check all connectors).
Why does the Olympus BX51 field of view become only slightly brighter?
If the field of view becomes only slightly brighter when the voltage is raised, the condenser is not properly centered (center the condenser) or the condenser is lowered too far (adjust the condenser height position).
Why is my Olympus BX51 bulb not lighting?
The bulb may not be lighting due to several reasons: the bulb is burned out (replace the bulb), the power cord is unplugged (plug the power cord into the power outlet), or the transmitted/reflected light switch is set to reflected light (for TRF models only, set the switch to transmitted light illumination).
What causes dirt in the Olympus BX51 field of view?
If you see dirt or dust in the field of view, it's likely due to dirt/dust on the eyepiece. Clean the eyepiece thoroughly.
Why does my Olympus Microscope stage drift down?
If the stage drifts down by itself or focus is lost during observation, the tension adjustment ring may be too loose. Try tightening the ring.
Why is the coarse adjustment knob on my Olympus BX51 Microscope hard to turn?
If the coarse adjustment knob is hard to turn, the tension adjustment ring may be tightened excessively (loosen the ring), or you are trying to raise the stage without the coarse adjustment knob while the pre-focusing lever is locked (unlock the pre-focusing lever).
Why is my Olympus BX51 bulb burning out quickly?
If the bulb burns out almost immediately, it's likely that the wrong type of bulb is being used. Ensure you are using the correct bulb type.
Why does my Olympus BX51 Microscope image appear to waver?
If the image appears to waver, the revolving nosepiece might not be correctly mounted (push slide dovetail all the way until it is stopped), the objective is not correctly engaged in light path (make sure that revolving nosepiece clicks into place correctly), or the condenser is not properly centered (center the condenser).
Why Olympus BX51 bulb operates but field of view remains dark?
If the bulb operates but the field of view remains dark, it could be due to several reasons. The aperture and field iris diaphragms may not be opened wide enough; adjust them to the proper sizes. Alternatively, the condenser might be lowered too much; adjust the condenser height position. Lastly, the light path selector knob might be set to the wrong position; move the knob to the correct position.
