New Page 1<br>Improve your View-Master Stereo Projection Experience with<br>NEW Polarizing Filters<br>for the Stereomatic 500<br>It is relatively easy to replace the polarizing filters in your View Master Stereomatic 500 Stereo Projector.  Simply remove the top cover (one thumb screws at the bottom) and then unscrew two large screws that hold the reel advance mechanism.  The polarizing filters are part of this assembly as seen  in the picture.<br>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).<br>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 on the right, polarization is reduced in the area heated by the light, vs. the one covered by the metal holder.  I have done this test above for the polarizers of the TDC projector but the idea is the same for any polarizing material (including viewing glasses)<br>I hope you enjoy stereo projection as much as I do...
