1. An optical measurement device, comprising:
a spectral optical system configured to disperse fluorescence emitted from a biological specimen;
an image sensor configured to:
receive the fluorescence dispersed by the spectral optical system; and
generate fluorescence information, wherein
the image sensor is divided into a plurality of regions,
each region of the plurality of regions is configured to receive a different wavelength component of wavelength components of the fluorescence, wherein the generated fluorescence information comprises information corresponding to the received different wavelength component of the wavelength components, and
the fluorescence information is image data including a value obtained by addition of pixel values, for pixels of the image sensor, for each of the plurality of regions;
a signal acquisition unit configured to calculate, based on the addition of the pixel values for each of the plurality of regions, an evaluation value of the fluorescence information; and
an analysis unit configured to:
analyze the biological specimen based on the evaluation value of the fluorescence information by the signal acquisition unit; and
display the evaluation value.
