JK(TM) Model: Linear Polarization
Note: This Clip On Linear Polarized 3D Glasses Works with IMAX Only
The polarization of this one is 0/90, please check the theaters
you enter in using the same glasses.
We also have another IMAX clip-on glasses whose polarization is 45/135. Enter into
our storefront and find the one suit for you.
Benefits of Linear Polarization
The process of linear polarization allows for lower light-loss than the process of circular polarization. Simply put, all things being equal with bulb
brightness, screen, and throw distance, IMAX 3D is brighter than circular-polarization 3D systems. The brightness of image for a 3D film is a common
complaint and almost all 3D systems suffer from significant light loss compared to 2D projection. This is an important factor for IMAX using Linear
Polarized 3D Glasses, as they aim for premium audiovisual presentation.
Benefits of Circular Polarization
If you tilt your head at all, linear-polarization cross-talk will drastically increase. You'll start to see combined images in each eye, ruining the 3D
effect and potentially giving you a headache. The same problem occurs with circular-polarization, but at a much lesser degree. Supporters of
linear-polarization believe that most people will immediately get that something is wrong when they tilt their head, and will adjust back to an optimal
viewing position. However, this makes a big assumption about how viewers will react to a suboptimal image and also places restrictions on the viewer that
might lead to physical discomfort while watching a long film. The MasterImage, Disney Digital and RealD Movies Using Circular Polarized 3D Glasses
