Abstract
Device for transmitting light at variable intensity, the device including a front variable polarizer, polarizing incoming light at a first selected polarization level, in a first direction and a rear variable polarizer, optically coupled with the front variable polarizer, polarizing light exiting the front variable polarizer at a second selected polarization level, in a second direction, wherein the first selected polarization level and the second selected polarization level are substantially zero, when no substantial electric power is applied respectively, to the front variable polarizer and the rear variable polarizer.
