Interferometric Verification
Fizeau and Twyman-Green interferometry, Shack-Hartmann wavefront sensing and MTF measurement.
Service Overview
Interferometry provides the most rigorous verification of optical performance. AISYS designs and operates Fizeau, Twyman-Green and Shack-Hartmann test setups to measure transmitted and reflected wavefront, MTF and surface figure to λ/50 accuracy.
Test-set design, reference-optic qualification and uncertainty budgets are all part of the deliverable — so measurements are defensible under audit.
