摘要： The present invention discloses a dark field illuminator for microscopic imaging, characterized in that, the dark field illuminator is arranged above an adjustable lens group of a unit microscopic imaging module and corresponds to the adjustable lens group, a surface of the dark field illuminator is attached to a back of a sample slide, and the sample slide is located between the dark field illuminator and the adjustable lens group; the dark field illuminator includes a bright and dark field substrate 4017 and a dark field black background patch 4018, the size of the dark field black background patch matches with that of the adjustable lens group, and the dark field black background patch is arranged close to or away from the adjustable lens group relatively to the bright and dark field substrate. Preferably, the bright and dark field substrate further has a recessed structure with a white diffuse reflection surface. The dark field illumine does not have a light source itself, which reduces a volume, and preferably, the dark field illuminator for microscopic imaging also has a bright field illumination structure and function, which can also be used as dark/bright field illumination alone, and can also be used for switching, so that the quick switching between bright and dark fields realizes integration and miniaturization of dark field illuminators and bright field illuminators.
