Abstract
A hand-held color measurement device is provided that includes a housing with a measurement unit which receives measurement light through a measurement window, converts it into measurement signals, processes the measurement signals to form digital color measurement data, and provides it via a communications interface. A U-shaped bracket is arranged on the housing and includes a middle portion in which a diffuser is integrated. The two side arms of the bracket are rotatably mounted on the housing such that the bracket can be pivoted by 180° from a monitor position to an ambient light position and back to the monitor position, and wherein the diffuser lies in front of the measurement window in the ambient light position and is situated at a rear wall of the housing opposite the front wall in the monitor position. A holding mechanism is provided on the housing and on the two side arms of the bracket which fixes the bracket in its monitor position or ambient light position, respectively. The hand-held color measurement device is simple in design and specially suitable for monitor, projection area and ambient light measurements.
