Queen-QCD IQC DOE Tester

Queen-QCD IQC DOE Tester

IQC DOE Tester is an innovative tester designed to test the imaging characteristics of DOE. Light pattern is captured and analysed for its characteristics through NIR sensitive camera and Lambertian Transmissive Diffuser to ensure it meets the stringent requirements. It is also equipped with soft handling capabilities to eliminate any damages onto the DUT.
