Microscope after Louis Francois Dellebarre (1770)

Louis Francois Dellebarre

This microscope was made after an idea of the French instrument maker Louis François Dellebarre. In 1770 he made an attempt to make a new kind of microscope. It should be completely without chromatic dispersion, just like the achromatic telescopes of the English instrument maker John Dollond. So the microscope had to supply a sharper image, without discolourations. Dellebarre's attempt to achieve this was not completely successful, but the quality of his microscope was so good for that time, that the product became very famous in the years around 1770. The ocular (the viewing part) is characteristic for Dellebarre-microscopes. It consists of a combination of four separate lenses, made partly of crown glass and partly of flint glass. In 1797 Dellebarre even added a fifth lens. The instrument makers Jan and Harmanus van Deijl were the first in the Netherlands who could copy the achromatic lenses of Dollond successfully. In 1806 they brought the first achromatic microscope on the market. Donation of Ms. J.C. van Vrede-van der Hoeven
