PURPOSE: A micro optic lens system is provided to correct effectively a comma aberration and a chromatic aberration by changing properly positions of a front lens group and a rear lens group as well as a refractive index. CONSTITUTION: A micro optic lens system includes a front lens group(100) having a negative refractive index, a rear lens group(200), and an aperture stop(300) installed therebetween. The front lens group is formed with a first lens to a ninth lens(1-9). The rear lens group is formed with a tenth to a thirteenth lens(10-13). The first lens(1) has a negative refractive index. The second lens(2) has the negative refractive index. The third lens(3) has the negative refractive index. The fourth and the fifth lenses(4,5) have the positive refractive indexes. The sixth and the seventh lenses(6,7) have the positive refractive indexes. The eighth and the ninth lenses(8,9) have the negative refractive indexes. The tenth and the eleventh lenses(10,11) have the negative refractive indexes. The twelfth and the thirteenth lenses(12,13) have the positive refractive indexes.
