Abstract:
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.
