| Dimension | Plano convex (flat convex) | plano concave( flat concave) |
| Shape | Middle thick, edge thin | Middle thin, edges thick |
| Focal Length | Postive f>0 | Negative value f<0 |
| Light path | converging parallel light | Divergent parallel light |
| Real object imaging | can form real images or virtual images | only upright and reduced virtual images |
| Aberration control | the spherical aberration is relatively small | Mainly introduce negatie ball difference |

Dimension
|
Plano conave lens( flat concave ) | bi concave lens ( double concave) |
| Structure | one side is flat, while the other side is concave | both sides are concave |
| Symmetry | Asymmetry | Symmetrical stucture |
| Minimum aberration condition | concave surface faces the beam with a large divergence degree | image conjugation(image positions can be interchanged) |
| Divergent thinking ability | relatively weak | stronger( with greater cuvature at the same focal length) strong |
| Typical application | beam boradening, focal extension, simple divergence | divergence, symmetrical optical path,aberration compensation |
