Intelligent whiteness meter/Working principle of intelligent whiteness tester:

The instrument uses an integrating sphere to measure absolute spectral diffuse reflectance, and its optical principle is based on the emission of a semiconductor light sourceblueThe colored light directly enters the integrating sphere,blueAfter diffuse reflection on the inner wall of the integrating sphere, the colored light is irradiated onto the sample at the testing port. The spectrum reflected from the surface of the sample is received and converted into an electrical signal by a silicon photovoltaic cell after passing through a condenser, light barrier, and color filter group; There is also a silicon photovoltaic cell that receives the substrate signal inside the sphere. The two electrical signals are amplified separately and processed by the microcontroller to achieve 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.

Technical Specifications:

1Diffuse illumination vertical detection method（d/o）。 This instrument complies with GB3978-83: Standard Illumination Body and Illumination Observation Conditions. It simulates D65 illumination body illumination and adopts d/o illumination observation geometry conditions.
