A stereomicroscope includes a base and a vessel which is disposed on the base. The vessel includes a transparent body and a light emitting unit. The transparent body has a bottom and a sidewall. The bottom and the sidewall define an opening. The sidewall extends from a side of the bottom. The opening of the transparent body places a specimen. The light emitting unit is fixed in the sidewall of the transparent body for emitting light. The light emitted from the light emitting unit illuminates the specimen, and is substantially parallel to the bottom of the transparent body.
