The interactive animation represents the geometric relationships described by the socalled lens equation.
You can zoom in and zoom out the rectangle in the animation by clicking on it.
The animation was developed as a offline application for Windows and Macintosh systems and for integration into Microsoft PowerPoint slides. The online version presented here serves as a preview. The exe or app file can be downloaded free of charge in the member area.
After the download, the animation can be displayed in full screen mode. Integration into PowerPoint is also possible.
The animation contains two areas with the following content:
Area  Description 

left  Example of an optical image with the most important rays 
right  The mathematical laws as formulas 
The focal length of the lens and the object height can be continuously adjusted via two controls. All the elements shown are continuously adapted in real time.
$f$: Focal length of the lens
$g$: Object distance
$b$: Image Distance
$G$: Object height
$B$: Image Height
The lens equation (also Newtons equation) is:
$$\frac{1}{f} = \frac{1}{g} + \frac{1}{b}$$
$f$: Focal length of the lens
$g$: Object distance
$b$: image distance
