Narrow viewing tank

This narrow tank allows optical experiments to propagate light in a medium. The parallel faces, thanks to their very good optical quality, allow a laser beam to pass without disturbance. The base guarantees good stability of the tank and the cover allows easy handling of the tank. The student thus carries out practical work on: - reflection / refraction - the limit angle of refraction in a context associated with optical fiber - observe the curvature of light with an index gradient to approach the principle of a mirage.
