WSD-3C Automatic Whiteness Meter Working Principle for Cosmetics, Flour, and Powder Whiteness Testing:

The instrument uses an integrating sphere to measure spectral diffuse reflectance. Its optical principle is to use blue light emitted by a semiconductor light source to directly enter the integrating sphere. After diffuse reflection on the inner wall of the integrating sphere, the blue light irradiates the sample at the test port. The reflected spectrum from the sample surface is converted into an electrical signal by a silicon photocell after passing through a condenser, diaphragm, and filter group; another silicon photocell receives the substrate signal in the sphere. The two electrical signals are amplified separately and processed by a single-chip microcomputer to realize the system functions of automatic zeroing, working white plate calibration, and sample testing. Users can easily use this instrument to test the whiteness of various samples.
