RGB Filters & Mirrors
KUPO Optics provides R/G/B filter that is able to divide those primary colors from the light source. For some specific optical instruments that require dividing R/G/B light, using this kind of filter is a very common and efficient solution.
On the other hand, the R/G/B reflection mirrors are designed for specific requirement of reflecting certain primary colors and let other colors go through.
