Disposal Information
This equipment has required the extraction and use of natural resources for its production. It may contain hazardous substances for health
and environment. In order to avoid the dissemination of those substances in the environment and to diminish the pressure on natural
resources, we encourage you to use the appropriate take-back systems. Those systems will reuse or recycle most of the materials of your
end of life equipment in a sound way.
The crossed-out wheeled bin symbol invites you to use those systems. If you need more information on the collection, reuse and recycling
systems, please contact your local or regional waste administrator. You can also contact us for more information on the environmental

1.1 Introduction
Function
The illusion of depth in a photograph, movie or other 2D image, is created by presenting a slightly different image to each eye. The
brain puts the two pictures together to form one 3D image.
The passive polarization 3D viewing system can be obtained with a dual projection setup.
In front of the lens of each projector, there’s a linear polarizer (reference 1, image 1-1). The polarization for the left eye is perpen-
dicular to the one for the right eye.
The light emitted by the projectors is projected onto and reflected by a special screen (reference 2, image 1-1) that is coated to retain
the polarization.
The images are simultaneously projected on the screen, so they overlap, resulting in a blurry image. But since the spectators are
wearing passive 3D glasses (reference 3, image 1-1) with perpendicularly polarized lenses, they can see clear and well defined 3D
images.

1.2 Installation process overview
Installation from A to Z
1. Stack the two projectors. The two projectors must be stacked using the multifunctional frame, which is exclusively designed
for the Barco RLM W-series projectors. See the installation manual (R5905038) of the multifunctional frame (R9899700).
2. Install the 3D polarizer assembly. The 3D polarizer assembly has to be mounted on the frame of the upper projector in the
3. Align the two stacked projectors. It is important that the projected images of both projectors coincide with each other on
the screen. See the installation manual (R5905038) of the multifunctional frame (R9899700) to align the projectors using the
adjustments on the frames.
4. Apply 3D content to the stacked projectors. For that connect the 3D content for the left eye with the input port of the lower
projector and the 3D content for the right eye with the input port of the upper projector.
5. Adjust the 3D polarization filters. For optimal 3D performance, the projected surface upon the polarization filters should be as
7. Enable/Disable the 3D polarization filters. For 2D projection, the polarization filter has to be removed from the front of the pro-
jection lens. The 3D polarization assembly is designed to shift the filters away from the projection lens. See "Enabling/Disabling

2. Installation procedures
2.1 Installation of the 3D polarizer assembly
How to install the 3D polarizer assembly?
1. Place the 3D polarizer assembly on top of the two stacked projectors as illustrated (image 2-1). If necessary, adjust the position
of the clamps (reference 1, image 2-1) on the frame in the Y direction (reference 2, image 2-1). Release the screws (reference
2. Secure the 3D polarizer assembly on the upper multifunctional frame by locking the clamps (reference 1, image 2-1).

3. Install the filter assembly with the filters in front of the projector lenses as illustrated (image 2-2). The upper profile of the filter
assembly has two guiding bolts (reference 4, image 2-2) which slide into the profile mounted on top of the projector. Tighten the
two knobs (reference 5, image 2-2) on top of the filter assembly to secure the position of the polarization filters.

4. Install the corner bracket (reference 6, image 2-3) upon the profile mounted on top of the projector as illustrated. Slide the corner
bracket against the filter assembly before fastening. Use a 4 mm Allen wrench to tighten the screw (reference 7, image 2-3) with
Note: This corner bracket functions as a reference for the filter assembly. In case the filter assembly was retracted for a 2D
projection it can easily be placed back in front of the projection lens by sliding the assembly against the corner bracket.

2. Installation procedures
2.2 Adjustment the 3D polarization filters
Why adjusting the 3D polarization filters?
For optimal performance of the 3D polarization filters, the projected surface upon the polarization filters should be as big as possible
without loss of content. The design of the 3D polarization assembly makes it possible to adjust the position of the filters in the X, Y
and Z direction.
This procedure assumes that the projected images of both stacked projectors are already aligned.
Why adjusting the 3D polarization filters?
1. Adjust the Y direction of the polarization filters until the center of the projected image matches the center of the polarization filter.
Release the two knobs (reference 1, image 2-4) to reposition the assembly with polarization filters. It may be necessary to release
Tip:
Once the Y direction is correctly aligned, install the corner bracket against the assembly with polarization filters. This
corner bracket will function as a reference to reposition the polarization filters for 3D projection after they were retraced
for 2D projection.

2. Adjust the height (Z direction) of each polarization filter until the center of the projected image matches the center of the polar-
ization filter. Release the two wing nuts (reference 3, image 2-5) to reposition the polarization filter. Tighten the wing nuts when
finished.

3. Adjust the X direction of the polarization filters, by sliding the upper frame away or towards the projection lenses, until the pro-
jected surface upon the polarization filters is as big as possible without loss of content. Release the two wing screws (reference
4, image 2-6) at both sides of the assembly to reposition the assembly. Tighten the wing screws when finished.

2.3 Cleaning the polarization filters
When cleaning the polarization filters?
Only clean the polarization filters in case it is really necessary. This means in case dust is clearly visible upon the surface of the
polarization filters.
WARNING: ISOPROPANOL ALCOHOL (200–661–7).
Hazardous product. Irritating to eyes and skin. Always use in a well ventilated area. Vapors may cause drowsi-
ness and dizziness. Avoid contact with skin and eyes. In case of contact with the eyes, rinse immediately with
plenty of water and seek medical advise.
CAUTION: ISOPROPANOL ALCOHOL (200–661–7).
Hazardous product. Lightly flammable. Always use in a well ventilated area. Keep away from sources of
ignitions. Do not smoke while working with isopropanol. Exclusive keep in original container tightly closed
at a cool, well ventilated and fireproof storage space.
Necessary tools
•
•
•
•
•
Compressed air.
Clean TorayseeTM cloth.
Clean cotton cloth.
Demineralized water.
Isopropanol alcohol.
How to clean the polarization filters?
1. Try to blow away the dust with compressed air.
2. Is all dust removed from the polarization filters?
If yes, stop this cleaning procedure.
If no, wipe off the dust of the polarization filters. Use for that a clean TorayseeTM cloth.
Caution: Always wipe in a single direction. Do not wipe back and forwards across the filter surface as this tends to grind dirt
into the coating.
Tip:
Limit the number of wipe movements. This to protect the optical coating. It is better to wipe of the dust with one good
wipe movement then with 10 soft wipe movements.
3. Is all dust removed from the polarization filters?
If yes, stop this cleaning procedure.
If no, wipe off the dust of the polarization filters first with a clean cotton cloth and demineralized water and than with a clean
TorayseeTM cloth.
Tip:
Use isopropanol alcohol instead of demineralized water to remove fingerprints.
Do not leave cleaning cloth in either an open room or lab coat pocket, as doing so can contaminate the cloth.
If smears occur when cleaning lenses, replace the cloth. Smears are the first indication of a dirty cloth.

2.4 Enabling/Disabling the 3D polarization filters
2D and 3D projection
The design of the 3D polarization assembly makes it possible to retract the filters from the lenses for 2D projection. The filters can
easily be placed back in their original position by sliding the filter assembly against the reference bracket.
How to enable/disable the 3D polarization filters?
2. Slide the filter assembly away from the lenses for 2D projection or slide the filter assembly against the reference bracket (refer-
