Spectral colour measurement of transparent materials

The two-part transmission sensor ACS3 includes a lighting unit transmitter and a receiver sensor which are positioned opposite one another in an axis. Transparent objects are placed between them and their colour is spectrally measured by the non-contact transmitted light principle. The colour of self-luminous objects can be detected as well for which only the receiver unit is required. The ACS3-TR5 receiver sensor measures at a distance of 100 mm with a measurement spot of 5 mm, whereas the ACS3-TR9 operates non-contact spectral colour measurement at a distance of 200 mm with a measurement spot of 9 mm. The maximum measurement distance is up to 300 mm.

The colour measurement system colorCONTROL ACS7000 achieves a colour value resolution of ∆E=0.08. Due to the high measurement frequency of up to 2 kHz, the measurement system is even suited to applications in production lines. The colorCONTROL ACS7000 can be used in car manufacturing, lighting systems¸ machine building, film industry, glass industry and plastics engineering. Operation, set up and configuration take place via a user-friendly web interface. Further features are: teach-button for fast colour storage, simple white/black adjustment, selectable standard observer and illuminant. Low ambient light influence ensures precise measurement values.
