magnification

The region of the highest cone density lies within the foveae, allowing the birds to clearly perceive distant objects through magnification.

Lenses with different curvatures will change the magnification of the telescope.

Magnification of common filters used in the home shows that, while they look like a solid piece of material with uniform holes, they are actually composed of millions of randomly oriented tiny voids that allow small particles to pass through.

"When the muscle contracts, all the force is converted into movement in that direction. It's a huge magnification."

By comparing the apparent positions of the holes as viewed by the optical microscope with the actual positions, the researchers assessed errors from magnification calibration and image distortion of the optical microscope.
