Light Flashlight
July 6th, 2010
How can I polarize the light coming out of a flashlight or old film projector?
Best bet is go to a good camera shop, and buy a “polarizing filter” and fit that over the flashlight or projector. Some ingenuity and/or duct tape may be needed to hold it in place, as the camera filter was designed to fit on a camera lens, not the flashlight or projector. A good polarizing filter will have a way to rotate it so you can change the polarization axis as needed, horizontal, vertical, anywhere in between, You can probably find a used one for $5 or so.
