Jasper County Democrat, Volume 2, Number 16, Rensselaer, Jasper County, 29 July 1899 — An Improved Microscope. [ARTICLE]

An Improved Microscope.

The microscope, as constructed heretofore only allowed the inspection of even surfaces, and its focus was bo limited that objects of any thickness had to be first prepared between glass plates or upon a flat surface to become visible at all. This quality makes it a most difficult matter to observe objects through a microscope of great enlarging power. In order to obviate this difficulty and to enable the enlarging of small bodies as well as of flat surfaces, an American living in Faris, Mr. Greenough, constructed a microscope with a greater depth of focus, which has since been further improved by the optician, Czapski, of Jena, Germany. Its lenses are so arranged that they will permit the inspection of uneven surfaces, and in order to make the vision mortT perfect, two systems of lenses are provided, giving the image a strongly 7 stereoscopic effect.
