Various optical adjustments are available, depending on your choice of lens. All lens
adjustments are motorized and controlled by the keypad, remote control or by RS232 or LAN.
Two kinds of lenses are available; fixed or zoom. A fixed lens has permanent focal length, or
throw ratio. A zoom lens has variable focal length or throw ratio.
In addition, fixed lenses may or may not be movable, depending on type and model. See the
specifications for the particular lens.
The throw ratio is defined as the ratio between the projection distance to the screen and the
projected image width. With a fixed lens, this ratio is set. With a zoom lens, this ratio can be
changed within certain limits specific to the lens in use.
On the keypad, first select lens function, then use the cursor keys to adjust. On the remote
control, zoom and focus are direct keys, while lens shift is operated by first selecting SHIFT then
use the arrow keys.
A mechanical SHUTTER is employed that totally shuts off the optical image path. The shutter is
directly available from the keypad and the remote control. The shutter is also in place when
there is no lens attached.
Select a lens suitable for the application. A range of lenses from very wide to super tele-zoom is
available.
Adjust the horizontal and vertical SHIFT, if applicable, in order to align the image on screen.
If a zoom lens is used, adjust the image to the right size. If a fixed lens is used, relocate the unit
to achieve the right image size.
FOCUS the image properly.
Adjust the IRIS to achieve the desired
optical balance between brightness
and contrast. In a bright environment,
brightness
is
usually
maximized
resulting in reduced contrast. In a dark
environment, less light is needed and
desired, while high contrast and deep
blacks are appreciated.
To level the image, adjust the feet as
needed
by
turning
the
feet
accordingly.
