Achromatism
Pronunciation: /ˈeɪsieɪtʃˈɹoʊˈmætˈɪzəm/
Achromatism (noun)
- A problem in optics where different colours focus at different points, causing coloured edges in an image.
- The degree to which an optical system avoids colour separation, so colours appear together at the same focus.
Examples
- The lens color error can blur colors at the edges.
- This lens color error appears when light focuses unevenly.
