Abstract
In order to be able to take an image of a specimen emitting low light in a short exposure time by a cooled CCD at about 0° C., a low-light specimen image pickup unit has an imaging optical system forming a specimen image of a specimen having a point light source emitting a low light, and the low-light specimen image pickup unit further has an image pickup unit having a plurality of pixels receiving incident light, for taking an image corresponding to the specimen image. In the low-light specimen image pickup unit, the imaging optical system is telecentric to a side of the specimen image of the imaging optical system, and condenses the low light emitted from the point light source to form an Airy disk of a size which is substantially the same as a pixel of the pixels, or which is smaller than the pixel. Here, the pixel receives the low light emitted from the point light source.
