Abstract: An apparatus is provided for measuring far-field luminous intensity and color characteristics of a light source that includes a lamp test location for receiving a lamp for testing and a mirror positioned in a fixed light receiving position relative to the lamp test location and positioned in a fixed light transmitting position for reflecting a light beam from the lamp at a predetermined angle relative to the light receiving position. A measurement screen is positioned in a location relative to the mirror to receive the parabolically-condensed light image reflected from the mirror at the predetermined angle and a light detector is positioned to capture a light image reflected from the measurement screen. The light detector is configured to convert the reflected light image on the measurement screen to a digital signal and output the digital signal.
