Two new reflectance colorimeters give spectral data for quality control of surface colour on regular surfaces or on small relatively inaccessible areas
John Morris Scientific has the Lovibond range of colour measuring instruments, which now includes two new reflectance colorimeters giving spectral data for quality control of surface colour.
The Lovibond RT100 consists of a compact, hand-held spectrometer unit with an integrated measuring head (45deg/0deg measuring geometry) for precision colour measurement and control of regular surfaces. The Lovibond RT200 includes a similar spectrometer unit but is supplied with a flexible, fibre optic measuring head (0/0deg measuring geometry) for colour measurement of small areas, challenging shapes or relatively inaccessible places.
The RT100 and RT200 combine advanced microspectrometer technology with the computing power of a PC.
The spectrometer units link to a standard PC computer with Lovibond RT colour measurement system software installed for instrument operation and for presentation, analysis and logging of reflectance data.
Results can be expressed in a choice of colour values and colour difference measurements: X Y Z tristimulus values, CIE L*a*b*, CIE x y Y, CIE L'u'v', CIE L*C*h*, whiteness index, yellowness index, DE, DL*, Da*, Db*, DC*, Dh* colour differences, reflectance, metameric index.
The software, which works under MS Windows 95/98/NT, displays a choice of colour spaces or reflectance curves; allows input and selection of reference values; will average multiple measurement; and includes a verbal indication of colour differences.
It includes the facility for data export to ASCII files and direct data export into MS Excel.
