How Calibration Targets Are Made: Photolithography, Chrome-on-Glass, and Acceptance Inspection
A calibration is only as accurate as the target it is derived from, so how a target is made is the floor the whole measurement sits on. Why photolithographic chrome-on-glass beats printing (sub-micron versus 50–300 µm edges), the five quality parameters that define a professional target, how chrome-on-glass is produced step by step, how substrate and chrome are chosen, and how CalibVision’s fabless model qualifies partners and inspects every finished part before shipment.
