A new color confocal microscope with high image quality and excellent color separation is implemented by using prismatic RGB light and receiving those RGB lights by corresponding three CCD image sensors. One CCD sensor consists of 4 million pixels (2048×2048) maximum and an image comprising of 12 million pixels is obtained as a result of 3 RGB image synthesis. Thus, a color confocal image with unprecedented good color separation and high resolution now can be displayed.
