A slit illumination device includes a first light-emitting element, a first diaphragm and a projection lens group. The first light-emitting element generates a primary illumination light. The first diaphragm has at least one opening and is disposed on a light exit side of the first light-emitting element, wherein the opening is an elongate shaped opening. The projection lens group is disposed on a light exit side of the first diaphragm, converging the primary illumination light and projecting it to a target object. A distance from the first diaphragm to the projection lens group is 1-2 times a focal length of the projection lens group on a light entrance side. The foregoing slit illumination device has advantages of simple structure, small size, and longer depth of field. A microscope system including the foregoing slit illumination device is also disclosed.

A contact-type ophthalmoscope includes a contact lens, an annular illumination module, an imaging lens group and an image capture module. The contact lens having a concave surface is configured for contacting an eyeball. The annular illumination module arranged close to the contact lens is configured for providing a direct illumination light source to illuminate a fundus of the eyeball. The imaging lens group is disposed in the central hollow portion of the annular illumination module and configured for converging the reflected light from the fundus of the eyeball. The image capture module is configured for capturing the reflected light converged by the imaging lens group to form an image. The above-mentioned contact-type ophthalmoscope has advantages of better illumination efficiency, compactness and less scattered light reflected from the imaging lens.
