The near-axial aberrations such as spherical aberration, coma aberration, and chromatic aberration are well corrected by computer optimization design. When used to focus the collimation, the surface ...
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 ...
Techspec MgF2-coated achromatic lenses from Edmund Opticsnow include F/1 versions and smaller diameters. Comprising two opticalcomponents cemented together to form an achromatic doublet, ...
