APPENDIX J : ADJUSTABLE LENSHOLDER

ADJUSTABLE LENSHOLDER

With BARCO's special adjustable lensholder, it is possible to shift the displayed

picture of a BARCOVISION 8100 projector up or down on the screen, without moving

the projector from its normal position, and without any geometric picture 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.) over 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 flight case.

can be calculated as follows:

Screen shift [mm/inch] = Lens shift [mm/inch] x 1+

To adjust the lensholder shift, handle as follow :
