Whiteness Colorimeter
Introduction: The instrument uses the integrating sphere to realize the measurement of spectral diffuse reflectance. The optical principle is to use the blue light emitted by the semiconductor light source to directly enter the integrating sphere. The spectrum reflected by the surface is converted into an electrical signal by the silicon photocell after passing through the condenser lens, light barrier, and color filter group; another silicon photocell receives the base signal in the sphere. The two electrical signals are respectively amplified and processed by a single-chip microcomputer to realize the system functions of automatic zero calibration, working whiteboard calibration, and sample testing. Users can easily use this instrument to test the whiteness of various samples.
