A rare 18th-century microscope magnification slider with five magnifications in complete condition.

By Gilgamesh

Comments Off

This is a rare 18th-century microscope with a magnification slider offering five distinct levels of magnification, and it is in excellent condition. While it could have functioned autonomously, however, the presence of the rail with the stops suggests it may have been part of a larger instrument. There are limited options for the maker of this instrument, as only a few manufacturers utilize such sliders. I’ll leave further research to more knowledgeable experts. Please also note the provided dimensions. Read More...

Biot’s polariscope by Pixii and Son, ca. 1835

By Gilgamesh

Comments Off

This is a rare early polarization instrument. The essential components for polarization, particularly the polarization prism named after William Nicol, had been developed by Edinburgh mineralogists William Nicol (1770-1851) and David Brewster (1781-1861) in the early 19th century.
