The interactive animation represents the geometric relationships described by the lens equation.
Click your mouse to zoom the rectangle in or out.
The animation was originally developed as a offline application for Windows and Macintosh systems and for integration into Microsoft PowerPoint slides. The online version presented here serve as a preview. The exe or app file can be downloaded free of charge from members area.
After the download, the animation can be shown 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 mapping with the most important rays 
right  Mathematical laws written as formulas 
The focal length of the lens and the object height can be freely adjusted via two controls. All elements shown are adjusted 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
