摘要
A target image-capture device may be configured to capture an image of a target that is made into plasma when irradiated with laser light and generates extreme-ultraviolet-light. The target image-capture device may include a droplet detector configured to detect passage of a droplet output as the target, and output a detection signal, an illumination light source, an image capturing element, a shutter device, and a controller configured to output, to the image capturing element, an exposure signal allowing the image capturing element to perform image capturing, and output, to the shutter device, a shutter open/close signal allowing a shutter to perform an open and close operation upon input of the detection signal. The controller may output the shutter open/close signal to the shutter device to make the shutter closed during when the droplet is irradiated with the laser light so that the plasma is generated.
