• the first lens group and the third lens group each has a negative optical power, the second lens group and the fourth lens group each has a positive optical power, the fifth lens group has an optical power of 0, a sum optical power of the first lens group, the second lens group, the third lens group, the fourth lens group, and the fifth lens group is 0;
• the lithography projection objective further comprises an aperture stop;
• and
• the first lens group, the third lens group, and the fourth lens group each comprises aspheric lenses, one aspheric lens of the aspheric lenses comprises an aspherical surface, and a number of the aspheric lenses is greater than or equal to 4 and less than or equal to 8.
