Reflection & Refraction

High-brightness LED Light Sticks RB-YB (Blue)

D20-1509-W4

【Product Description】

LED light stick (blue) 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 (blue). When used with Light Stick(s) of other color(s) (white, red, and white), 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.
