Compound microscope

Cylindrical tube microscope with the eyepiece and lens at the ends. The latter is supported by an arm that joins it to the pillar, acting as a support for the tube. The quadrangular pillar has a rack system, which is controlled with a side screw, to move the stage vertically away from and toward the sample for macroscopic focusing. The stage is round with a large central hole containing a device that uses a spring system to hold the sample in place inside it. The stage also has side holes for clips. The front face of the pillar houses the plano-concave mirror. The base is made up of 3 legs joined to a central axis. One is thicker than the others, which fold up onto it.
