Q-factor

The Q-factor in optical metrology acts as a benchmark for the surface quality of optical components and their ability to reflect or transmit light efficiently without causing losses or scattering. This key figure is particularly important in applications where precise light manipulation is required, for example with lenses and mirrors.

To achieve a high Q-factor, critical parameters such as surface roughness, uniformity and material purity must be carefully controlled. Precise management of these factors ensures that optical distortions are minimized and optical systems can perform to their maximum potential. The Q-factor plays a central role in the manufacture and quality inspection of optical components and is used to assess their suitability for high-precision optical applications.
