   Circular Polarizer 3D System ?
   which should I select ?
  Linear polarizer system is suffice for most 3D theatrical environment where audiences sit still with their head position fixed during the show.
However, for those with where audiences' head is moved and shaken
constantly like in a theme-park ride, circular polarizer system is preferred.

 How Does Polarizer 3D work ?

The human brain composes surrounding 3D image
from
parallax. Using same principal, it is possible
to recreate artificial 3D image by having two
cameras shooting the object from two slightly
different perspective. By letting the only right eye
see the image captured with right camera and
only left eye see the image captured with left camera,
it enables to see stereoscopic images on a 2D screen



   Linear Polarizer 3D System

Light is blocked when two linear polarizers are stacked in a manner that
their respective absorption axes are set at perpendicular to each other,
and light is transmitted when absorption axes are set at parallel.
Linear 3D polarizer setup above applies this principals and allows only right eye
to see right projector image, and left eye to see left projector image,
creating 3D (stereoscopic) image in the viewer's brain as a result.



   Circular Polarizer 3D System

 
Light is blocked when Left & Right polarizers are stacked with respective
retarder film sides facing each other. Circular 3D polarizer setup above applies this principals and allows only right eye to see right projector image, and left eye to see left projector image, creating 3D (stereoscopic) image in the viewer's brain as a result.
Note :
@ The rotating axis (of projected image) is reversed when reflected on the screen
Therefore, it is required to use left circular polarizer for right eye projector, and vice versa.
A Circular polarizer maintains light blockage even when the relative angles is altered.
Yet, blockage is most efficient when absorption axis are set at perpendicular to each other



   Linear & Circular Polarizer Film / Glass for 3D Projector

Super durable linear polarizer MUHD40S (Dye type & High heat resistance) is recommended
for linear polarizer 3D system. For circular polarizer system, we have MCPR / MCPL 
(retardation at 140 nm) and also CP125R / CP125L (retardation at 125 nm).
Please select the one compatible with your particular 3D glasses.
High heat resistance Linear and Circular Polarizer Glass for 3D projection are also available.
Polarizer film MUHD40S is sandwiched in between optical glass. In addition, precision ground finish prevents image distortion and thus capable to produce a crisp 3D image.

Notice :
Due to its catadioptric effect, regular white screen inhibits optical property
of polarizer film (making it difficult to separate left and right images)
Therefore, please make sure to use high refraction 3D silver screen for 3D projection
