Binoculars - DIY STEM Educational Toys

The first function of the telescope is to magnify the opening angle of distant objects so that the human eye can see details with a smaller angular distance.

The second function of the telescope is to send the light beam much thicker than the pupil diameter (maximum 8 mm) collected by the objective lens into the human eye, so that the observer can see the faint objects that were previously invisible.

In 1608, Hans Liebesch, an optician in the Netherlands, accidentally discovered that he could see distant scenery with two lenses. Inspired by this, he made the first telescope in human history. In 1609, Galileo Galilei, a Florentine, Italy, invented the 40-fold binocular telescope, which was the first practical telescope to be put into scientific application.
