Learn more about the spectro2guide PRO and how it provides reliable results in color, gloss and fluorescence measurement, as well as Jetness measurement of deep black colors. (https://www.byk-instruments.com/en/Co...)
What makes the spectro2guide Pro so special?
It has always been the greatest challenge for a spectrophotometer to achieve repeatable and reproducible results on a black color.
While a white sample reflects almost 100 percent of the light emitted by the spectrophotometer, the proportion of reflected light becomes smaller and smaller with darker colors - as increasingly larger amounts of light are absorbed by the sample. Consequently, the so-called "signal to noise ratio" changes with dark colors: The measurement signal decreases while the thermal noise, which is basically caused by electronic components, remains constant. Measurements of innovative, deepest black coatings with very low reflection takes place at a lightness value of L* smaller than 1. This is a challenging task for a measurement instrument and pushes the technical performance of a handheld spectrophotometer to the utmost limit.
