ROTATIONAL ZONE TOTAL REFLECTION ILLUMINATION MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a rotational zone total reflection illumination mechanism in which an illumination without polarization even at the periphery of a visual field is given and a fluorescence information of all directions is available. SOLUTION: In a Koehler type illumination system in which an object is illuminated by introducing laser light to the peripheral part of an objective lens of a microscope, the rotational zone total reflection illumination mechanism is characterized in that the direction of illumination with the laser light is rotatable around the axis of the objective lens 56 of the microscope.
