Nakamura Optical Bench, For Student Use

Enables 3-dimensional observation of the movement of light through a lens.

Here are 3 experiments to demonstrate how a lens works with sunlight and the path of light entering and leaving the point of convergence:

1. An experiment using the magnifier and sunlight:
*Attach the magnifier into the magnifier holder.
*Adjust the direction of the magnifier directly toward the sun to cast an image of the sun on the white screen.
*Images corresponding to the convergence pattern of the projected image will appear on the series of transparent screens.

2. An experiment with two-colored filter:
*Continue from experiment 1.
*Insert two-colored, red and green, filter into the front of the magnifier.
*The red and green pattern of the two-colored filter will appear directly on the screen located between the lens and the point of convergence.
*A small, white image will appear on the screen at the point of convergence.
*A reverse pattern will appear on the screen located some distance away from the point of convergence.

3. An experiment with a triangular window screen:
*Continue from experiment 1.
*Insert a triangular window screen into the front of the magnifier.
*A reversed triangular image will appear on the screen located some distance away from the point of convergence.
