Examples of Investigation and Measurement

Alignment of the system
The experiments begin with the positioning and alignment of all the optical modules. Placing them in the proper way will allow imaging an inserted mask on a screen or on a white wall.

Lens equation
By varying the distances of the modules or by changing the objective lens the image can be changed in size. On this set-up the lens equation is demonstrated impressively. Magnification as well as 1f- and 2f-arrangements are discussed.

Spatial selection
With a variable aperture the light beam can be pinched at different positions on the optical bench. Filtering close to the mask is spatially selective, whereas filtering in the region of the lamp image attenuates the whole picture.
