Abstract
It is possible to save time and effort required for imaging of an analysis point and to improve usability of an analysis device. An analysis and observation device as a laser-induced breakdown spectroscope includes: a first camera, an electromagnetic wave emitter that emits laser light to a sample; a reflective object lens that collects plasma light generated in the sample; first and second detectors that generate intensity distribution spectra; and a processor. The processor controls the first camera in response to reception of a start trigger signal to generate a pre-irradiation image that is an image before the sample is irradiated with the laser light, and controls the electromagnetic wave emitter after controlling the first camera to emit the laser light to the sample.
