- Abstract
In this work, we substituted rod lenses by the cylindrical body of clear plastic Light Emitting Diodes (LEDs), as a cheap laser line shaping optical element, for physics classroom demonstrations and experiments. A laser pointer was used to test three different LEDs, to reveal the correlation between their diameters and the beam fan angle. The results show that the performance of the LED body with smaller diameter was the best in terms of maximum laser line length. This application is useful in pedagogic activities, low cost optical designs, large field automotive shadowgraphy and non-Doppler laser shadow vibrometry of incandescent linear objects.
