The image on the left and the diagram on the right come from a terrific online exhibit about Galileo's microscopes, the Museo Galileo in Florence.Īnother interesting English-language resource is the University of Oklahoma's recent online exhibit Galileo's World. The microscope on the left, perhaps designed by Galileo (1564-1642), is attributed to Giuseppe Campani (1635-1715), in which case it would have been made after Galileo's death. None of the microscopes that Galileo used has survived. It did not magnify much more than his telescopes, about 30 times, but Galileo was more interested in the multitude of stars he could see through his telescope than in the insects he examined close-up with his microscope. This Galileo SS-80090TR 800mm x 90mm Astronomical Reflector Telescope and Galileo G-SPA Smartphone Adapter kit lets you use the camera feature on your Smartphone to take pictures or video through the optics of your telescope, or use your smartphone to assist navigating your telescope view to your celestial object of interest.
His first microscopes, in 1609, were basically little telescopes with the same two lenses: a bi-convex objective and a bi-concave eyepiece.īy 1624, Galileo had developed an occhiolino (the word microscope was not coined by Giovanni Faber until the following year) that had three bi-convex lenses.
However, using lenses with a shorter focal length, he could, in effect, turn the telescope around and magnify little things.
It did not take him long to realize that getting a longer focal length with his telescopes was a big problem.
