Up to scratch?

For decades, the standard method of measuring the surface quality of optical components has relied on visual inspection and human judgement. Although this may be adequate, many have scrutinised the approach for not being quantitative enough for performance-based specifications.

There has been pressure to replace subjective inspections with objective tests that can be documented in order to reduce incoming rejection rates, prevent disruption to work flow, and improve customer-supplier relationships.
