This action allows specific colors to be extracted. Applications Applicable to color TV cameras, LCD projectors, photographic color enlargers, color facsimile, illumination and other optical systems. Used for diagonal incidence. Reflects a specific region of light and transmits other regions. Separates the three primary colors of blue, green and red from white light. Can also combine the three primary colors into white light. Blue-reflecting mirror R400 - 450nm >/= 95% T490 +/- 10nm = 50% T535 - 700nm >/= 85% Green-reflecting mirror T500, 580 +/- 10nm = 50% T420 - 470nm >/= 80% T620 - 700nm >/= 80% Red-reflecting mirror T420 - 550nm >/= 85% T590 +/- 10nm = 50% R640 - 700nm >/= 95% Used for normal incidence. Selective transmissioin of a specific region of light allows a specific color to be extracted. 6 types of filter are available depending on the difference in transmitted colors.
