LASER OPTICAL TANK

The Laser Optical Tank is an educational optics apparatus designed to demonstrate the fundamental principles of reflection, refraction and total internal reflection. It provides a simple and effective way for students to observe the change in direction of a light ray as it passes between different optical media.

The apparatus consists of a transparent acrylic tank mounted on a sturdy plastic base with levelling screws for accurate positioning. A 150 mm diameter graduated dial/protractor is provided for measuring and setting the angle of the incident light ray. The rear side of the tank carries a clearly printed angular scale for convenient observation and measurement.

A pivoting arm with a battery-operated revolving laser source directs a narrow beam of light into the tank. The tank can be partially filled with water, allowing the laser beam to travel through air and water and making the path of the light ray clearly visible.
