Patented infrared sensor technology with CONESPLIT® Same Spot

CONESPLIT® Same Spot Technology uses a patented measuring procedure to directly (selectively) measure layer thickness online which is a globally unique selling point of Protagon.

Special features:

Simultaneous and same spot scanning of the spectral properties of the web by using 6 parallel optoelectronic channels
Measuring wave lengths are selected specifically for the application. Therefore only information-including ranges of the possible spectrum are used, and redundant information as is common for full spectrum analyzers is avoided, which significantly enhances the measuring speed and simplifies the calibration procedure
Splitting of the measuring beam with virtually no losses to the wavelength specific detectors
Very high signal level and signal-to-noise ratio
Simultaneous use of the near IR and mid IR spectral ranges allows measuring of the absorption band that yields the maximum resolution for the given coating substrate

Customer benefits of the CONESPLIT Same Spot Technology

Selective measuring using only one measuring point
Very high measuring precision
Non-nuclear technology without safety requirements
Operation does not require official approval
No falsification of measured results as all filters are supplied with information obtained from the same measuring spot, irrespective of the web movement
Up to 6 parallel measuring channels
Wide IR spectral range (1-4 μm) with pre-selected wave lengths
Computation and output of all wave lengths and measuring channels in less than 10 ms
Not sensitive to optical disturbances, therefore thin layers may be measured as well
Long-life IR source, therefore no routine maintenance is required
