Reflection & Refraction

High-brightness LED Light Sticks RB-YG (Green)

D20-1509-W3

【Product Description】

LED light stick (green) emitting “belt-like” high-brightness single beam

【Overall Advantages to Users】

  • Possible to emit a linear ray bright and well-defined enough for tracking even in a classroom under normal illumination level. Thanks to the built-in light source unit called “Beam LED” that emits about 17mm-thick “belt-like” beam in a vertical direction developed by Narika Corporation.
  • This Light Stick emits a single beam of a single color (green). When used with Light Stick(s) of other color(s) (white and/or red), it will be possible to create two or three parallel beams, or convergent or divergent beams emitted from random angles.

【To all users】

  • Possible to emit even brighter and better-defined linear ray than any other similar product because the Light Stick uses its built-in “Beam LED” to emit a single ray only, unlike Narika’s “Ray Box L-2 (D20-1507-W0)” of which the light source is split into three rays.

【To teachers】

  • Students’ safety is secured because LED that is much less harmful for eyes than laser is used for the light source.
  • Dark environment is no longer needed to observe reflection, refraction, convergence and divergence of light.
  • Easy to demonstrate by mounting the Light Stick on metal surface like a whiteboard owing to the built-in magnet on the back.
    -Portable because it is powered by dry cell battery.
    -Easy to manage students’ activities because experiments can be carried in a classroom with normal level of illumination (with lights on).

【To students】

  • Reflection from and refraction by an object with a certain thickness will be clear and well-defined because of the 17mm thick beam in a vertical direction compared with laser beam (typical point light source) and conventional LED light source without such thickness.
