Abstract: An immersion objective, an optical system and a detection method. The immersion objective sequentially comprises, in the direction from an object side (S) to an image side, a first lens group (G1) having a positive focal power, at least one group of lens groups (G5, G6) having a negative focal power, and an immersion medium (m) which is located on the object side (S) of the first lens group (G1) and immerses at least part of the first lens group (G1), wherein the working distance S0 of the immersion medium (m) between the first lens group (G1) and the object side (S) and the focal length Fobj of the immersion objective satisfy the conditional expression 0?S0/Fobj?0.16. By means of the cooperation of a plurality of groups of lenses, an immersion objective has a relatively small size and a relatively low mass within a relatively compact size range, and a large field of view, a high resolution and a low distortion are achieved, thereby improving the optical performance of the immersion objective.
