Laser Internal Reflection: a green 532nm laser pointer is directed down a section of bent acrylic rod- exhibiting internal reflection which constrains most of the laser light to propagate along the interior of the rod (similar to the physics of fiber optics). The acrylic sample is actually a specially made particle detector component called a scintillator that contains chemicals that fluoresce green when exposed to ionizing radiation, and the internal reflection properties shown here direct any

Reflection and Refraction of a Cyan Laser Pointer: an affordable laser pointer with a color that’s pretty new on the market- 488nm producing a beautiful hue of blue. The beam is made brightly visible as internal reflection constrains most of the laser light to propagate along the interior of this block of acrylic (similar to the physics of fiber optics). ➡️ Follow the link in my profile for info on where to get a cyan laser and clear demonstration block like these and other amazing items feature
