Project

Why I did this project?Because from this project, we can know that dome shaped lens can be used to make a simple camera.  Even this camera can’t take any pictures, but we can see the pictures from the screen.

What do you need for this project?

-            -  A Scissor

-            - Carton (thin duplex)

-            - Black tape

-            - Dome shaped lens (from magnifier)

-             - Oil paper

What is the steps?

1.       Find the focus from the lens

    Ø  Every dome shaped lens has a focus, we can now it by light the lens, and then make rest of the light is only a dot. Find the distance from the lens until the dot.

2.       Make a cylinder to put the lens, the cylinder must as long as the focus of the lens

    Ø  Make it as long as the focus, then put the lens at the end of the cylinder

3.       Make a box with different side on the two sides

    Ø  Make a box with the length of the side same as the lens’s focus. But, in one side, make a hole for place the cylinder. And the opposite side, make a hole (square shaped) to put the oil paper as the screen. Make sure no lights can get in except from the cylinder (lens)

4.       Make another box without top

    Ø  Make a new box without top and the length of sides is focus length, focus length, and half focus length. On the bottom side, make a hole (circle shaped) that not too big for place where we look into the screen. Stick with the first box and make sure that no lights can get in. We have to look the screen in dark condition.

5.       Finish.

    Ø  Now, you can use your camera, but in your screen, you will look upside down.

What is the result?

The result is the simple camera, this camera is can be seen from old camera. The camera in old times, show the picture upside down.
