Abstract: A universal microscope stage is described herein. The universal microscope stage can comprise a slide holder, a base mount, a first rack, a first driver, and a first pinion. The slide holder can be capable of holding a slide in a fixed position relative to the slide holder. The base can comprise a plurality of mounting orifices aligned across the base mount. The first rack can be mounted to the base mount. The first driver can comprise a first pinion orifice. The first pinion can extend through the first pinion orifice. The first pinion can interface with the first rack such that when the first pinion rotates, the first driver can move the slide holder along a first axis relative to the base mount.
