1. Before Setting Up Your Projector
1.2
Selecting Primary/Anamorphic Lenses for Your
Projector
This section provides guideline information on how to select a screen size and projector
mounting position appropriate for your presentation purposes and about selection of types of
lenses as well. Select primary/anamorphic lenses for your projector according to the
environment in which it is installed.
Note that all descriptions given in this manual suppose that the angle of projection is zero
degree. Therefore, you need to calculate the projector tilt/pan angle so that it can be
minimized during projection when you project slides downward or from a side.
1.2.1
Screen Type
The following two types of screen masks can be used for the DLP Cinema Projector. Check
the screen mask for your projector for its type before selecting lenses because types of
primary/anamorphic lenses to be used on the projector and its settings depend upon the
type of screen mask you use.
Horizontal moving screen mask
Screen masks move horizontally to
adjust the screen.
Vertical moving screen mask
Screen masks move vertically to adjust the
screen.
1.2.2
Selection of Anamorphic Lens
An anamorphic lens is required when you use a wide screen for projection. Because a
different type of anamorphic lens should be used according to the type of projector and
screen, determine an appropriate anamorphic lens in consultation with the end user,
considering its application purpose. See the table below for available anamorphic lenses.
