	Jansen (crater) - Wikipedia, the free encyclopedia
		Jansen is lunar crater in the north part of the Mare Tranquillitatis.
		The rim of Jansen is low and narrow, while the floor has been covered by lava.
		To the northwest of the rim is a rille named Rima Jansen, and to the east are wrinkle-ridges in the mare surface.

	PHYSICISTS AND MEDICINE
		Zacharias Jansen and his father Johannes Jansen of Holland in the year 1590, discovered the principle of microscopy and telescopy by placing two lenses together in a tube.
		Having heard of Jansen's discovery of the microscope and the telescope, it was he who for the first time in 1609 in Italy, used lenses for magnifying objects.
		Armed with a telescope he embarked on the study of astronomy and saw the four moons of Jupiter - the discovery which was in keeping with Copernicus' theory that the sun was the centre of the solar system and not, as was believed then, the earth.

	The First Compound Microscope:
		Since Zacharias was very young at that time, it's possible that his father Hans made the first one, but young Zach took over the production.
		As was customary at the time, the Jansens made several versions of their new invention to give to royalty.
		While neither of these instruments survived to modern times, the later of them was preserved until the early 1600's, when a Dutch diplomat and childhood friend of Zacharias Jansen named Cornelius Drebbel, examined it and recorded his observations.

	Advances in Microscopy - Biocompare Technology Spotlight
		It is difficult to imagine the study of biology without the use of these tools, so it is somewhat surprising that the facts surrounding the invention of the microscope are a little unclear.
		It is generally thought that a Dutch man, Zacharias Jansen, produced the first microscope, around 1595.
		The Jansen microscope was a 2-lens, compound microscope that allowed for a magnification range of 3-9X.

	KryssTal: Feedback (Astronomy - Page 1)
		Most likely the basical techniques of both microscope and refractor-telescope were invented around 1590 by Zacharias Jansen, a very young spectaclemaker - some say he was only a child - from Middelburg in the Netherlands (not Denmark).
		Hans Lippershey was a competitive spectaclemaker from the same city of Middelburg who may have used the inventions of Jansen for his own sake.
		Anyway, his patent request in 1608 was not granted, because Maurits, the prince of Orange, allready posessed a telescope made by Jansen for many years.

		Optical microscopy has come a long way from Zacharias Jansen´s first microscope at the end of the 16th century to today´s highly developed microscopes.
		A number of different contrast mechanisms allows broad applicability as a routine tool in biologiy, medicine, materials research, and many more.
		One should look at it as a complementary tool with some room for improvement.
