Abstract: A handheld, portable color measuring device (10) for measuring the primary colors of red, green and blue in a color target (22) and connected to a built-in LCD display (30) or connected to a separate personal computer (38). The color measuring device (10) includes an elongated color measuring probe housing (12). A hollow cone shaped probe tip (18) is attached to one end of the probe housing (12). Inside the probe housing (12) is a battery powered white LED light source (42) connected to a color measurement switch (26). A light pipe (44) is centered inside the probe housing (12) and a portion of the probe tip (18). The light pipe (44) captures the light reflected off the color target (22) and projects the captured light onto a 3 color sensor (54). The light signal is amplified and converted to a digital signal using an A/D converter. The A/D converter is part of a microprocessor mounted on a printed circuit board (56) inside the probe housing (12).
