Reflection & Refraction

Optical Fiber Theory Set


[Product Description]

Pair of Translucid Lenses for Learning Optical Fiber Theory

[Overall Advantages to Users]

  • Introductory educational material for optical fiber theory.
  • Suitable for demonstrating optical fiber’s theory by observing internal reflection of light ray of laser beam transmitted inside the translucent S-shape lens and straight shape lens.


  • Optical communications
  • Optical fiber
  • Reflection/refraction and linearity of light

[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.
