LABSCAN-Screen
Laboratory Inspection of Automotive Glass




Inspection Task                                             Benefits

LABSCAN-Screen has become a well-known                      •   Reliable and repeatable measurement
standard in the car glass industry to control                   of transmitted distortion instead of
optical distortion in the laboratory. The propri-               subjective visual methods
etary Online-Moiré-Technology ensures real,                 •   In general: comprehensive quality ana-
reliable and repeatable measurements with the                   lysis and assessment
highest resolution and accuracy.
                                                            •   Offline sample testing or process
Application                                                     control at production sites
                                                                Supports design studies for new deve-
     All screens: windshields, back lites and side lites.       lopments at R&D and quality centers.
     All directions: horizontal and vertical distortion         Comparable results to SCREENSCAN-
     (float optic)                                              Faultfinder
     All glass types: clear, coated and dark glass
     (insensitive to fingerprints and dust)                     Measurement results are comparable
     Optional: measurement of reflected distortion              to existing quality standards
     for side lites                                             Quick and easy visualization of results,
                                                                user-friendly operation.
The system provides comprehensive measurements
with highest precision. The screen may be measured
at different positions and tilt angles to analyze distor-
tion for their effect and cause. Distortions are meas-
ured with numerical accuracy in millidiopter for best
performance and statistical information. The measur-
ing results are directly comparable to the inline
inspection system SCREENSCAN-Faultfinder.
