The On-Line color measurement system ERX54 is a non-contact
spectrophotometer to measure the production of non-scattering samples
like glass panes directly on the production machine. Functional layers
like low-E or solar protection can be measured and quantified. Beside
the color values, the spectral curve, measured and displayed from 330
nm up to 730 nm will provide detailed information about the
reflectance. Optionally the transmission can also be measured.
The ERX54 illuminates the pane with +15° and
measures the reflected light at -15°. This ensures the same readings on
the production machine as in the laboratory. Functional layers like
solar protection or low-E glass can be measured and controlled. The
special optical design allows distance variations to the glass surface
of up to 30 mm without any mechanical adjustments.
A new design allows much faster measurements. These measurements are transmitted via CAN-Bus to the computer. Optionally
a second ERX54 can be mounted on the other side of the pane. This
allows a reflectance measurement from both sides and the transmission
measurement.
