Description
A rare dark-field stage microscope by Nachet called by himself “ultramicroscopie”. The stage bears the serial number “75” and its signed “Nachet”. It is complete and in fine condition, preserved in its original box, also signed.“Dark-field transmission or ultramicroscopy illumination “: […] Objects whose dimensions are all smaller than the resolution limit are invisible in bright-field lighting. But the existence of these “ultramicroscopic” objects can be perceived by taking advantage of diffraction. In the dark-field microscope, or ultramicroscope, only the condenser or stage are different from that the other microscope”.
Both holes in the stage are later. There is two screws, certainly used in the past to fix the stage on a microscope.
A rare Nachet accessory.
