NONLINEAR OPTICAL MICROSCOPE AND METHOD FOR ADJUSTING SAME

摘要

PROBLEM TO BE SOLVED: To provide a nonlinear optical microscope that can surely maintain the efficiency of detecting light rays high, and to provide a method for adjusting the nonlinear optical microscope. SOLUTION: The nonlinear optical microscope includes a scanning means (16) that scans an object with spot of illuminating light formed by an objective lens (17), and a detection means (200) that detects signal light having nonlinear intensity relation to illuminating light from the spot on the object. A standardization beam diameter ϕ=ϕf/ϕothat is a ratio of a pupil diameter ϕoof the objective lens to a luminous flux diameter ϕfof the illuminating light projected to the objective lens is set to be near a specified value that gives a peak to the intensity of the signal light under a condition that power of the illuminating light going toward the objective lens is constant.
