Technical details and manufacturing context for Interferometric Measurement Head

Definition
The interferometric measurement head is a critical component of the Precision Optical Lens Centering Machine, responsible for non-contact measurement of lens centering errors, surface tilt, and optical axis alignment through laser interferometry principles. It provides micron-level accuracy for quality control in optical lens production.
Working Principle
Utilizes laser interferometry where a coherent light beam is split into reference and measurement paths. The measurement beam reflects off the lens surface, recombines with the reference beam, creating interference patterns that are analyzed to determine precise displacement, tilt, and centering parameters.
Common Materials
Optical glass, Stainless steel, Aluminum alloy
