Improve your Stereo 3D Projection Experience with
4x4 inches NEW Polarizing Filters
You are getting one pair of filters
It is easy to replace the polarizing filters in your Stereo Projector with a pair of NEW filters.
Use the original pair to trace over the new filters and then cut with scissors. Make sure the pairs are aligned (look clear not black/dark).
One question in many people's mind is "how do I know if I need new filters or not?"
All plastic polarizing filters deteriorate through time and under the intense heat of the light bulbs
. If you notice "ghosting" then it is possible that you need new filters (
note
: ghosting can be caused by other factors like  the screen or the photographic emulsion of the film - ghosting means that the left eye sees part of the right image and the right eye sees part of the right image, i.e. the polarization is not good).
Here is a simple test anyone can do to test polarizing filters
:
Cross the filter with a pair of viewing polarizing glasses
until it gets as dark as possible and look at a bright light source, such as a panel of fluorescent lights.  If the picture is overall dark (deep blue, as in the left picture above) then the filters are good.  If the picture is light then the filters are no good.  Notice that in the picture, polarization is reduced in the area heated by the light, vs. the one covered by the metal holder.
I hope you enjoy stereo projection as much as I do... I was (and still am) our stereo club's film projectionist. I started with a TDC 116 projector and later upgraded to an RBT projector. I carry a variety of projection related products in my ebay store, like glasses and other polarizing filters.  If you have any questions, feel free to contact me.
