Classification: CPC G  H | IPC G  H

Claim 0:
1. An ionization device configured to generate ions by irradiating a sample with laser light, the ionization device comprising:
a light source configured to emit laser light;
a light collection optical system configured to collect laser light emitted from the light source and irradiate a sample with the laser light;
a first intensity changing unit including an attenuator configured to continuously change an intensity of laser light with which the sample is irradiated;
a second intensity changing unit including a darkening filter configured to stepwisely change an intensity of laser light with which the sample is irradiated;
a storage unit configured to store a relationship between a irradiation diameter of the laser light, a level of changing the intensity of the laser light of the darkening filter, and the intensity of the laser light irradiated with the sample; and
at least one processor configured to
receive input of an irradiation diameter of laser light to the sample;
receive input of an irradiation intensity of laser light to the sample; and
change an irradiation diameter of the laser light by means of the light collection optical system;
control the second intensity changing unit according to the irradiation diameter received based on the relationship; and
set an intensity of the laser light with which the sample is irradiated by controlling the first intensity changing unit according to the irradiation intensity based on the relationship.
