The figure you use to measure the quality of the polarizer is the &#8220;extinction ratio,&#8221; which is the ratio of the minimum and maximum transmitted intensities. For an ideal polarizer, this would be zero&#8211; perfectly polarized light would be completely blocked by an ideal polarizer at 90 degrees from the light polarization&#8211; but nothing is perfect, so there&#8217;s always a little bit of light leaking through.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Uncertain Principles: How Good Are Polarized Sunglasses?
