Instruments Spektralapparat von C. Steinheil, M nchen, ca. 1895 Spectroscopic instruments have also contributed significantly to our present scientific knowledge. Without their very precise analysis results the fast development of chemistry would not have taken place. The composition of our sun and other stars could be unriddled with the help of spectroscopy, too. Two demonstrations explain how a prism and a grating spectrograph work.
Endoscopes play an important role in medicine today.
A bundle of elastic thin glass fibers is their most important component. The visitor learns about their function and how they are manufactured. A demonstration lets him look into an artificial windpipe, the way a physician would see it with the help of a bronchoscope. Photometers are used to measure the intensity of light. Originally developed to determine the luminosity of stars, their scope has become significantly larger.
