Abstract
Fluorescence observation apparatus includes laser scanning fluorescence observation unit and wide field fluorescence observation unit. The former unit includes: lasers; scanning unit that scans sample by laser light; and detector that detects fluorescence from the sample excited by the laser light. The latter unit includes: light source to planar-illuminate the sample; excitation filters that are selectively arranged on light path from the light source, and that correspond to the lasers, respectively; and two-dimensional detector that detects fluorescence from the sample excited by light that has passed through excitation filter arranged on light path from the light source. Each of the excitation filters has optical property in which center wavelength of transmissive band is approximately the same as oscillation wavelength of corresponding laser and bandwidth of transmissive band is approximately the same as tolerance width of oscillation wavelength of corresponding laser.
