Factors That Effect Quality |
 |
The quality of an optical system such as a lens is a crucial factor in microscopes for accurate observation.
Some indicators which signal the performance of a lens are resolution, brightness, depth-of-field, monitoring distance, aberration, and so on.
These factors are proportionately taken into consideration when microscope lenses are designed. |
|
Resolution |
|
| A high-resolution lens allows detailed and accurate observation. |
|
Brightness |
|
| Detailed observation cannot be performed with a lens that produces a dark image. |
|
Depth-of-field |
|
| A lens with a large depth-of-field, allows even odd-shaped objects to be brought into focus. |
|
Monitoring Distance |
|
| This is the distance between the object and the lens. The greater this distance, the further the degree of freedom allowed for observation. |
|
Aberration |
|
| This refers to color smudges and distortions of an image. This can be compensated for by combining multiple lenses. |
