Reflection & Refraction

Circular Cylinder Lens


[Product Description]

Circular cylinder lens, with one white colored side, suitable for demonstrating how a rainbow is formed based on the properties of light such as dispersion, refraction and reflection.

[Overall Advantages to Users]

Unparalleled product because a circular-cylinder-shaped lens is not commonly available but indispensable for reproducing rainbow-like spectrum in labs.

Conventionally, learners learn how a rainbow is formed only out of their textbooks, etc. without conducting experiments. As opposed to such conventional learning method, this product is intended for learners to reproduce and analyze a rainbow-like spectrum in person.


  • Dispersion, Reflection, and Refraction of Light
  • Refractive index (refraction index)
