Tristimulus filters consist of three distinct color filters designed to match the color sensitivity of the human eye. Semrock Tristimulus Optical Filters provide the lowest available deviation (f1’) from the responses defined by the 1931 CIE standard observer model, ensuring precise color matching and minimal error. These filters are crucial in optical systems that aim to replicate or enhance human visual perception. High-quality tristimulus filters are ideal for machine vision, scientific systems, and surgical/medical applications to accurately match the human eye spectral response.
