Discovery Microscope is the perfect introduction for any student and science lover. It has the same optical qualities of many professional tools. This microscope has a straight hollow tube with a 160mm focal length so that it can also be used for photography. It has a dual focus adjustment, macro- and micrometric fine adjustment on both sides and a light condenser lens to regulate the incoming light. There is also a solid, stable metal stand which can be inclined up to 90 degrees for comfortable observation. The whole;comes with an anti-dust cover and a CD-Rom.
From ancient times, man has wanted to see things far smaller than could be perceived with the naked eye. Although the first use of a lens is a bit of a mystery, it’s now believed that use of lenses is more modern than previously thought.
However, it has been known for over 2000 years that glass bends light. In the 2nd Century BC, Claudius Ptolemy described a stick appearing to bend in a pool of water, and accurately recorded the angles to within half a degree. He then very accurately calculated the refraction constant of water.
During the 1st century AD (year 100), glass had been invented and the Romans were looking through the glass and testing it. They experimented with different shapes of clear glass and one of their samples was thick in the middle and thin on the edges.
