Magnification and Resolution
OHT Master 6
The image is composed of dots.
No amount of magnification will
reveal any more detail or information ie; nothing more can be
resolved.
Magnification increases the
apparent size of an object.
Resolution is the ability of an optical system to distinguish between
adjacent points.
