1. An optical system (1) for imaging an object plane (100) to an imaging plane (200), the optical system comprising
said object plane (100), said imaging plane (200), a first tunable lens (10) arranged between said object plane (100) and said imaging plane (200), said first tunable lens (10) comprising
a first fixed container (11) made of a rigid material,a first deformable membrane (12) made of an elastic material, anda first fluid (15) enclosed by at least said first container (11) and said first membrane (12), a second tunable lens (20) arranged between said first tunable lens (10) and said imaging plane (200), said second tunable lens (20) comprising
a second fixed container (21) made of a rigid material,a second deformable membrane (22) made of an elastic material, anda second fluid (25) enclosed by at least said second container (21) and said second membrane (22), at least one fixed correction lens (30,40, 50,60) made of a rigid material and arranged between said second tunable lens (20) and said imaging plane (200), wherein an Abbe number of each of said first fluid (15) and of said second fluid (25) is larger than 60, in particular larger than 80. |
