Portable Color Sensors Handle UV Effects.Quick analysis of uv light absorption and extremes of gloss on plastic surfaces typically requires an expensive benchtop spectrophotometer spectrophotometer, instrument for measuring and comparing the intensities of common spectral lines in the spectra of two different sources of light. See photometry; spectroscope; spectrum. . But that has been changed by the launch of CM-2600d and CM-2500d portable models by Minolta Corp.'s Instrument Systems Div. in Ramsey, N.J. Both feature a 52mm integrating sphere, dual-beam geometry and illuminated sample viewer. A novel capability is "instant" calibration and adjustment when measuring samples that contain uvabsorbing fluorescent colorants or optical brighteners Optical brighteners, optical brightening agents, fluorescent brightening agents or fluorescent whitening agents (FWAs) are dyes that absorb light in the ultraviolet and violet region of the electromagnetic spectrum, and re-emit light in the blue region. . As a result, users can acquire simultaneous results with uv light included and excluded. A second new feature is faster and more accurate measurement of samples with gloss differences, without need to change the set-up of instruments or samples. Glossy and non-glossy samples can be measured with specular spec·u·lar adj. Of, resembling, or produced by a mirror or speculum. spec  u·lar·ly adv.Adj. 1. components included and excluded simultaneously. Both models store up to 700 measurements in on-board On board usually means to be traveling on some vehicle. For example, Baby On Board. Compare with overboard. Metaphorically, the term on-board is often used to refer to some piece of technology that is integrated in a moving vehicle, for example: |
