Compound microscope Power switch and rheostat - to adsjust the amount of light Objective Revolving nosepiece - to switch from one objective to another objective Base - to hold the microscope during transportation Illuminater/light source Fine adjustment knob - to fine tune the focusing of the image Coarse adjustment knob - to move the stage or the objectives for focusing on the object Pinion knob - to move the condensor unit for focusing the light on the slide Arm - to hold the microscope during transportation Condensor and iris diaphragm - condensor to focus the light on the slide and iris diaphragm to adjust the amount of the light passing through the slide Stage - to place the slide for observation Body tube - for light to pass from objectives to the oculars Oculars or eye pieces - to view and magnify the image of the object

Objective lenses Oil-immersion lens (100X) - allows you get a total magnification of 1000X High-dry objective lens (40X) - allows you get a total magnification of 400X Low-power objective lens (10X) - allows you get a total magnification of 100X Scanning objective lens (4X) - allows you get a total magnification of 40X Revolving nosepiece - to switch from one objective to another

Stage Opening in the stage to allow light to pass Iris diaphragm lever - to adjust the amount of light going to the slide Illuminator/light source Coarse adjustment knob - to move the stage or the objectives for adjusting the focus Fine adjustment knob - to fine tune the focusing Base Knob to move the mechanical stage and the slide back and forth Knob to move the mechanical stage and the slide Mechanical stage - to hold the slide and be able to move it up or down or sideways Stationary stage - to place the slide for observation

Condenser Arm - to hold the microscope while transporting it Base Light switch/rheostat - to adjust the amount of light going to the slide Iris diaphragm and lever - to adjust the amount of light going to the slide Stage - to place the slide Condenser - to focus the light on to the slide Blue filter - to get a hogher resolution image Illuminator/light source Pinion knob Coarse adjustment knob - to move the stage or the objectives for focusing on the image of the object Fine adjustment knob - to fine tune on the focusing
