In a method for operating a microscope, a lens unit transmits a first image laser to an object, and acquire a first scan image on the basis of a first reflection signal reflected from a first area included in the object. An ultrasound conversion unit transmits an ultrasound signal to the first area and focuses same so as to form air bubbles in the first area. The lens unit transmits a second image laser to the object, and can acquire a second scan image on the basis of a second reflection signal reflected from the second area included in the object. The ultrasound conversion unit transmits an ultrasound signal to the first area included in the object and focuses same so as to form air bubbles in the first area, thereby enabling an increase in the imageable depth of a microscope.
