層したことを特徴とする光学フイルター。 Three polarizing plates are stacked and installed with their phases changed, and are brought into contact with each of the polarizing plates to allow the total amount of light from two of the three different colors to pass through, while the other colors pass through. An optical filter characterized in that three pieces of colored glass for attenuating light are attached, and a single polarizing plate that can be rotated to a position adjusted to the phase of the three polarizing plates is laminated.
