Patent ID: 8310754

Claim:
A laser excitation fluorescent microscope, comprising: a light collecting part collecting at least two types of excitation lights radiated by laser light source part on a sample; a dichroic mirror, disposed between the laser light source part and the light collecting part, making the two types of excitation lights incident on the light collecting part by reflecting the two types of excitation lights, and transmitting two types of fluorescence generated at the sample in accordance with the two types of excitation lights; and a detecting part detecting each of the two types of fluorescence transmitted through the dichroic mirror, in which the detecting part includes a plurality of detectors, wherein an incident angle θ of the excitation lights and the fluorescence to the dichroic mirror is smaller than 25°, and a transmittance of each of the two types of fluorescence to the dichroic mirror is 95% or more.
