Surface inspection for displays, car displays, and high-gloss enclosures

The quality control of reflective or transparent components is one of the most demanding tasks in optical metrology. Phase-measuring deflectometry is considered to be a particularly reliable optical measurement method. In this field, ISRA VISION has set standards with the SpecGAGE3D sensor family and perfected the procedure for automated inline measurements of highly reflective objects.

 

Learn in our brochure how to automatically detect form deviations and surface defects on displays, car displays, optical components, and housing parts and how to sort out defective parts.

Smartphone displays: quality control before and after the display layers are joined together

When the various display layers are joined, imprints on the cover glass and other defects can occur that cannot be detected with the bare eye, However, they canimpair optical properties and function. 

The automatic optical surface inspection with SpecGAGE3D reliably detects local defects such as unevenness, carrier structures, or so-called read-throughs before or after joining the display layers.

Head-up displays & deflection mirrors

Head-up display deflection mirrors must be perfectly shaped and coated because this is the only way they can produce optimal imaging. Form deviations of the deflection mirrors or defects on the coating can interfere with imaging and thus impair driving safety. Automated inspection with SpecGAGE3D reliably detects shape deviations and surface defects in just one measurement pass. Thanks to 100% inspection, only flawless mirrors are delivered.

  • Production optimization with clear defect classification and traceability
  • Fully automatable: 24/7 continuous operation
  • Reduced allocation of human resources
  • Form deviations
  • Inclusions
  • Scratches
  • Unevenness
  • 100% defect detection and form control for reflective or transparent surfaces
  • Shape and defect inspection in one measurement
  • Determination of stable and comparable values
  • Multi-Part Inspection: Simultaneous measurement of multiple parts in a tray

Car Display

Concave shapes are being used more and more frequently, especially in the automotive sector, because the displays require less space for the same display size. At the same time, they place increased demands on quality inspection because, in addition to the flawless surface and optical quality, the fitting accuracy and shape must also be exactly right.
The SpecGAGE3D inspection system from ISRA VISION inspects the shape and surface of curved and flat displays and cover glasses as well as plastic optics such as the light guide in just one measurement pass, thus enabling reliable and highly efficient quality control for car displays.

High-gloss housing parts

Scratches, inclusions, or paint runs on high-gloss housing parts from the end consumer market  disturb the appearance and can lead to costly complaints. The production integrated automatic surface inspection with SpecGAGE3D detects cosmetic defects quickly and reliably, reveals process weaknesses, and ensures comprehensive quality control.
