Colour Control of Translucent Liquids, Semi Solids & Opaque Samples

Low cost system based on enhanced microspectrometer technology

Colour control from batch to batch is an important quality characteristic for many translucent products. The eye can easily detect differences in colour and, if two samples of the same product have a noticeable colour difference, then the consumer may judge the product to be of poor quality because of the colour inconsistency.

The RT100 Translucence Spectrophotometer is a compact colorimeter, giving spectral data for colour control of translucent liquids and semi solids. It consists of a spectrophotometer unit with an integrated 45degrees; / 0degrees; measuring head, mounted in a light-excluding funnel that houses the translucent samples in tubes. The design establishes a standardised sample presentation and measuring technique, which guarantees that colour data are repeatable and that sample comparisons are of significance, in particular:

* A specific sample path length, which must be fixed, as the colour of a translucent sample is dependent on its path length;

* A constant sample environment, an important feature because some of the light from the spectrometer is transmitted through the sample;

* Exclusion of ambient light, which can affect measurements.

* For colour control of opaque samples, the spectrometer unit can be removed from the funnel.

The RT100 Translucence Spectrophotometer combines advanced microspectrometer technology with the computing power of a PC. The spectrophotometer unit links to a standard PC computer with software installed for instrument operation and for presentation, analysis and logging of reflectance data. The recommended colour scale for translucent samples is CIE L*a*b* although results can be expressed in the following choice of colour values and colour difference measurements: X Y Z tristimulus values, CIE L*a*b* colour space, CIE x y Y chromaticity coordinates, CIE L’u’v’ colour space, CIE L*C*h* colour space, Delta E, Delta L*, Delta a*, Delta b*, Delta C*, Delta h* colour differences, Whiteness Index, Yellowness Index, Reflectance, Metameric Index.
