ColorLite – Your specialist for spectral colour measurement Officially founded in 2003, the origin of our success lies back in 1997. When Light emitting diodes – LED’s – were evolving from a simple, low intensity light source to a super high power light source, which was robust, had a comparable low power consumption and almost infinite lifespan. LED has revolutionized the lighting industry back then – and it was our idea to use this progression to develop a new system for measuring colours on a professional level. PhD Student David Pryor at the University of Applied Sciences, Hannover, together...

ColorLite · Spectral Colour Measurement Online / Inline ColorLite – Your advantages at a glance • We offer tailor-made complete solutions to determine colour values production-related. With customerspecific measured value output and forwarding to your process control system. High-resolution colour information enables, among other things, perfect automatic control of your colour dosage and saves time-consuming and delayed offline measurements in the laboratory. Optional thermochromic measurement to determine and compensate for temperature-related colour deviations. Modular design for reflection...

Spectral Online-/InlineColour Measurement Colour values measured in real time during production are good value for money. For an efficient and resource-saving production, a fully automatic monitoring process is essential. Spectral colour measurement is the most accurate measuring method to achieve constant and the most reproducible measurement results. The samples are measured with the homogeneous white and blue light illuminated by high-power LEDs. The surface of the product is spectrally scanned in 3.5nm steps. Coordinates in a wavelength range from 400 to 700nm are output in different colour...

ColorLite · Spectral Colour Measurement Online / Inline „We use only LED‘s as light source for our spectrophotometers!

Advantages of the LED light source: • LED‘s guarantee a service life of at least 20 years • Highest permanent repeat accuracy of the measured values. • Replacement and maintenance of the light source is not necessary, thus reducing time and costs. • The emission spectra, including the UV component, are variably adjustable. • LED´s are small, compact, and robust. • No change of the spectral values over the runn

Service Software Accessories Probe heads Spectrophotometer Application example ColorLite ■ Spectral Colour Measurement Online / Inline Transmission measurement of foils The industrial production process of coloured plastic foils requires continuous control of the colour. This is made possible by our online spectral colour measurement systems in combination with a dosing unit. The spectrophotometer permanently monitors the production and at the same time regulates the colour additions.

Application example Reflection measurement on a running steel strip The colour is checked during production immediately after the steel strip leaves the coating furnace. At this point, the plates have a temperature of about 60°C. To compensate for the thermochromic properties, the surface temperature is measured with an infrared sensor for further colour calculation. The probe heads can be moved automatically to different positions and adapt to the different widths of the steel strip.

Application example Strand measurement For the first time, colour measurement on the strand or extrudate in compound production or extrusion offers a very cost-effective solution with a reduction of measuring and reaction times, which reduces production errors to an exceptionally low level. The system was developed as part of a publicly funded joint project between SKZ Plastics Centre in Würzburg and ColorLite GmbH. Our cooperation with the SKZ Würzburg In close cooperation with SKZ, the Plastics Centre Würzburg, we develop spectral online colour measurement systems for the plastics industry....
