Guide and labeled diagram: https://yenra.com/diagram-of-microscope-parts/
Use with the manual for your exact microscope. This refers to an upright
compound microscope with suitable prepared slides and dry objectives.
Model / manual location:
Locate: eyepiece, head, arm, nosepiece, objective, slide holder, stage,
condenser, aperture iris, coarse focus, fine focus, illuminator, base.
Also locate: power, brightness, stage movement and any photo selector.
Before viewing: select low objective; position specimen; use manual's
starting clearance and focus sequence. Keep objective clear of glass.
Before higher power: center the feature; check clearance; refine focus.
Dark view: check power, illumination, objective position and light path.
Lost feature: return to low power; recenter; focus before trying again.
Resistance or drift: stop forcing controls; check the manual or seek service.
