The On-Line color measurement system ER56PA is a non-contact spectrophotometer to measure the production of non-scattering samples like glass panes directly on the coating machine.

The On-Line color measurement system ER56PA is a non-contact spectrophotometer to measure the production of non-scattering samples like glass panes directly on the coating machine. Functional layers like low-E or solar protection can be measured and quantified with 2 different measurement angles. Beside the color values, the spectral curve, measured and displayed from 330 nm up to 730 nm at both angles will provide detailed information about the reflectance.

The two angle measurements simulate an observer at a large distance to the building (±15°) or very close to the building and looking into the reflected sky (±60°).

Optionally the transmission can also be measured simultaneously.

The ER56PA 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. A second flash lamp illuminates the sample at +60° and measures at -60°. Functional layers like solar protection or low-E glass can be measured and controlled even at different angles. The special optical design allows distance variations to the glass surface of up to 16 mm without any mechanical adjustments. The measurements are transmitted via serial interface to the computer. Optionally a transmission head can be mounted on the other side of the pane to measure the transmission spectral curve.
