Colour Measurement
Process Monitoring on
Vacuum Coating Plants

Process description
OPTOPLEX is a new measurement and analysis
system for the use in vacuum coating plants. it allows
non-contact and destruction-free measurement ofspectral transmission and colour data both in andoutside vacuum plants.Measurement and analyticalresults are suitable as proof of quality and serve forprocess optimisation.OPTOPLEX II P is customised fortransmission measurements in vacuum.
Measurements are taken on architectural glass,butalso on car window panes, displays, acryllic glassor plastic films.The systems provides measurementog single and multi-layer coatings.

System description
The system serves for quality control in glass coatingprocesses inside vacuum chambers.It collects the.data of a transmission measurement carried out by
the system itself in the running production process

and displays the results graphically and numericallyon the screen of the control computer.

Software

The software allows display of spectra or of
the trends of one or several measuring
stations.
The system determines the transmission fordifferent standard illuminants (A, C or D 65)
and viewing angles (2° or 10°).

The program can handle up to 10 measuring
stations.The measured spectral curves areconverted into the corresponding CIELAB dataconsidering the selectable standard illuminants
and viewing angles.

Colour Measurement
Quality Control of
Coating Processes

Process description
A great number of applications, suchas panes,
displays, etc.cannot be imagined today without
the use of glass. this is due to its properties suchas transparency,chemical stability,environmentalcompatibility,scrach resistance.The optical andthermal properties of glass can be influenced.

Vacuum coating is a technique that can give glass
such particular properties. By vacuum coating,ultra-thin layers are applied to the glass surface.
To achieve the desired quality of the coatings it isvery important to monitor the applied layers.

System description
The system serves for quality control after thecoated flat glass has passed throughall technicalproduction processes. The system collects the dataof transmission and reflection measurements
performed by the system itself. It calculates thecolour data accordingto CIELAB, and displaysthem graphically and numerically on the screen of
the control computer.The measuring heads arefirmly mounted to a carriage traversingon a rail.
The measuring heads are controlled andpositioned in such a way that measurements canbe taken at any point of the surface andunderside. The measured resultscan be used as
proof of quality according to ISO 9000.

System description

Software
The software contains two program modules:

1.
2.

Parameter Setup & Manual Operation
Automatic Process Control

1. Parameter Setup & Manual Operation
In Parameter Setup, measuring heads andmeasurement parameters can be set. Besides, itallows selection of nominal light data,
tolerance limits, lateral positions and definitionof the measurement process.
The manual operation option serves for testing
and assessing the selected parameters.

2. Automatic Process ControlIn the Automatic Process Control Module, themain menu provides display of the trends of meanvalues and the dispersion compared with thetolerance zone.
In running measurements, the system can display
current data distribution across the scanned area,
out-of-range data and results of precedingmeasurement series. In addition, the user can load
complete methodologies.
