Curvature measurement in Automotive glass.

Curvature measurement in Automotive glass.

Curvature measurement in Automotive glass.

  • A laser based curvature measurement system for automobile car glass
  • To measure the curvature, the laser system mounted on an actuator, moves across the glass and measures multiple locations
  • This laser beam reflected from the glass and received at the mirror
  • Based on the variation of height, the curvature is measured.
  • A user friendly software developed for data logging and for mapping curvature in waveform

ADVANTAGE

  • Can measure under harsh condition(glass temp 1000° C and ambient temp 250 ° C)
  • Laser not jittered by varying glass curvature or its physical properties
    High capturing speed (ie) reduced inspection time
  • Accuracy of ±1 mm
  • Repeatability : ± 0.2mm
  • Economical compared to other similar systems
