FormatChanger
We change from landscape to portrait format optically
The VICOM
Format Changer optically changes the format from landscape to portrait. This is
a
necessity during numerous
projections at events and advertisements. Many users turn their
projector by
90° onto the side. This, however, can lead to cooling problems and a
problem in
stability, due to missing adjustment legs. Many producers of
projectors prohibit projection on the
side.
The Format Changer, developed by VICOM, can be used for slide, video and data
projectors. The Format Changer
is placed in front of the lens and changes
the picture from landscape to portrait. The quality of the picture will not
be affected.
Format Changer is available in two different models. These depend on the
lenses and their different image ratios.
A lens with the image ratio of 2:1
needs another optical component than one with 5:1.

What is an image ratio? It tells you which ratio the lens has regarding
distance to width of the picture. For example:
the distance of the projector
to the screen is 4 m and the projected picture is 2 m wide, the ratio will be
calculated
accordingly: 4/2. In this case the image ratio is 2:1.
