We developed a radiation-resistant camera that can acquire color images. A mosaic-patterned RGB filter was fabricated using dielectric thin-film stack technology on a radiation-resistant glass wafer. The spectral transmittance for each color was controlled by adjusting the thicknesses of the middle and top layers of the stack. Bonding a fabricated filter and a monochrome image sensor was carried out, aligning the position by monitoring the image signal. The acquired images exhibit good color reproductivity.
