# Screen

The screen is used to capture and display real images formed when simulating ray diagrams. It consists of a screen part and a display which shows the image captured on the screen. To see an image appear on the screen, you must place the screen over an image that is formed when you set up a ray diagram.

Tips for use:

- When you resize the screen, the display will resize automatically, as its size is directly related to that of the screen itself.
- The display can be moved away from the screen and placed anywhere within the optical space, on top of any other part. However, it will always display the image captured on its associated screen.
- Note that the screen can only display real images. You can view virtual images using the eye.
