[To all users]

• Since material of lens is translucent (translucid) plastic, the laser beam line in the lens is observed clearly.

[To teachers]

• Portable and easy to demonstrate anywhere.

[To students]

• Easy to observe how laser beam is transmitted by repeating reflection at the inner surface of the lens.
• Easy to clearly observe the track of laser beam because of the lens type.
• Easy to confirm that, by changing the angle of incidence, the number of repeated reflections also changes.
• Easy to confirm that beam that exceeds the critical angle of incidence will be radiated outside the bar.
• Easy to confirm that same property of the beam (reflection) can be obtained regardless of the shape of the two lenses.
