Abstract

AbstractA device is presented for non‐mechanical switching between transmission of red, green, and blue spectral bands. The ColorSwitch™ developed specifically for projection systems uses a unique two‐polarizer additive‐mode design. Three retarder stack‐based stages are cascaded, each independently operating on an additive primary. Attributes of the color switch include high transmission, fast switching, wide color gamut, wide acceptance angle and high power handling.
