Adjustable lensholder Features and Principals.

With 'Adjustable lensholder', it is possible to shift the displayed picture of the projector up or down on the screen, without moving the projector from its normal position, and without any picture geometric distortion. This system is particularly useful for use in dual or triple projector configurations, or for applications where the projector can not be installed in its standard position.

Features:

- Vertical shift of the lens possible between 20 mm (0.79") up and 6 mm (0.24") down without removing the projector cover.

- Shift of the displayed picture on the screen up till 2 meters (6.5 ft.) above its standard position.

- Makes it possible to project a geometric non-distorted picture from a non-standard projection position. - The shift of the lensholder is not determined by the lens used, but depends on the screen width.

- Can be used with all available lenses.

- Can be used in dual or triple configuration in combination with BARCO's projection frame or multifunctional flightcase.

The vertical shift of the picture on the screen (Y-axis on diagram) is function of the screen width (X-axis) and the shift of the lens in the projector. The shift of the displayed picture can be calculated as follows:

	(		Screen width [m/inch]
Screen shift [mm/inch] = Lens shift [mm/inch] x 1+
			LCD panel width (1) [m/inch] )
		(1) LCD panel width: 0.118 m (4,646")
