Device for the measurement of reflections on coloured objects

摘要

The device is intended for the measurement of reflections on coloured objects. According to the invention, at least three photocells (7) are arranged in the measuring head (5') of the housing above the measurement opening (1') which can be illuminated uniformly all around at 45 DEG . Arranged between the measurement opening (1') and the photocells (7) for the purpose of subjecting them uniformly to measurement light are light-guiding elements inside a tubular light-shielding diaphragm (9) with an aperture angle of at most 10 DEG . The photocells (7) are bound in in a light-tight fashion at the upper end of the light-shielding diaphragm (9). <IMAGE>
