The low or medium power objective lens is usually 10x magnification and is also used for scanning.
The high power lens is usually 40x or 100x and is used for detailed viewing of a specimen.
Spooky Cell 3 I can make some people scream and squeal, But to Edward Cullen I am a favorite meal.
What’s my power? To calculate the power of magnification, MULTIPLY the POWER of the Ocular Lens by the POWER of the Objective What is the power of magnification for the Ocular Lens (shown) and the 40x Objective Lens (shown)? Fill Your Calculations AND Your answer on Your Worksheet!!!
Comparing Powers of Magnification We can see better details with higher the powers of magnification, but we cannot see as much of the image. Which of these images would be viewed at a higher power of magnification?

Don’t use too much or the water will run off the edge and make a mess! 3 – Place the edge of the cover slip on one side of the water drop. You do not need to use the stage clips when viewing wet-mount slides! 5 – Place the slide on the stage and view it first with the red-banded objective.
