The achromatic doublet lens is used to minimize or eliminate chromatic aberration. Its achromatic design also helps to minimize spherical aberration. Compared with a single lens, an achromatic doublet ...
An achromatic lens is a lens that is designed to limit the effects of chromatic and spherical aberration,and is corrected to bring two wavelengths (typically red and blue) into focus on the same plane ...
Researchers developed a new way to apply anti-reflective coatings to 3D-printed multi-lens systems such as the doublet objective pictured here, which is just 600 microns in diameter. These coatings ...
