Product Overview
Lumirod – Optical Fiber Model for Total Internal Reflection
The Lumirod demonstrates the principles of total internal reflection and its application in fiber optics. Light directed into the polished bottom end of the rod undergoes multiple internal reflections as it travels through the coiled structure, finally emerging from the other end. Made from high-quality Lucite® acrylic, the Lumirod is 16 inches long and wraps into two circular coils, providing a clear visual of light behavior in optical fibers.
Recommended use: Pair with a red or green laser pointer for optimal results.
Available options:
-
Lumirod alone
-
Lumirod set with red laser pointer (650 nm, <5 mW output) housed in a durable stainless steel shell. The laser operates on three LR41-type button cells (batteries not included).
