Parts the the Microscope:



Your microscope has actually 4 target lenses: Scanning (4x), short (10x), High (40x), and also Oil Immersion (100x). In this lab, you will not use the oil immersion lens; that is because that viewing microorganisms and also requires technological instructions not extended in this procedure.

You are watching: How do you find total magnification

In addition to the target lenses, the ocular lens (eyepiece) has a magnification. The total magnification is established by multiplying the magnification that the ocular and objective lenses.

Magnification Ocular Lens Total Magnification
Scanning 4x 10x 40x
Low Power 10x 10x 100x
High Power 40x 10x 400x
Oil Immersion 100x 10x 1000x

General Procedures:

1. Make certain all backpacks, purses, etc. Are off the benchtop.

2. Lug the microscopic lense by the base and also arm with both hands.

3. Keep with the cord wrapped approximately the microscope and the scanning target clicked into place.

Focusing Specimens:

1. Plug her microscope into the strength supply and also switch on the illuminator.

2. Constantly start with the phase as low as feasible and making use of scanning target (4x). Odds are, you will have the ability to see miscellaneous on this setting (sometimes it’s just a color). Use the rough circuit knob to focus: the photo may be little at this magnification, however you won"t be able to find it on the greater powers without this very first step. Move the mechanical phase until your focused image is likewise centered.

3. Once you"ve concentrated using the scanning objective, move to the low strength objective (10x). Use the coarse knob to refocus and move the mechanical phase to re-center your image. Again, if you haven"t concentrated on this level, you will not have the ability to move to the following level.

4. Currently switch to the high strength objective (40x). In ~ this point, only use the good adjustment knob to focus specimens.

5. If the specimen is also light or also dark, try adjusting the diaphragm.


1. Store microscopic lense with the scanning objective in place and also the phase in its lowest position.

2. Wrap cords around the microscope.

3. Change slides to initial slide tray.

1. Utilizing the carry pipette, carry a autumn of pond water onto a microscope slide. The ideal specimens typically come indigenous the bottom and probably will certainly contain chunks of algae or other debris the you can see through your naked eye.

2. Location the coverslip top top the slide.

3. Usage the SCANNING (4x) objective to focus, then move the mechanical stage around to scan the slide for live microorganisms. You are in search of tiny swimming beings- they might look eco-friendly or clear and might be very small. Select one to focus on and also center the in her visual field.
