4.3 Calibration Process

The calibration process for a DLP PGU has 3 main steps that make up the process from prototype through production.

Pre-production steps:

  • Calibration Pre-work: Coarse combination determination
  • Temperature characterization

Production steps:

  • Production PGU calibration
