Advances in optical metrology equipment are helping the semiconductor industry increase productivity and reduce downtime, finds Keely Portway
In deflectometry, a camera images fringe patterns that have reflected off a surface under test, so that a system can deduce a map of the surface slopes from the deviation of the projected fringes, and from that determine the surface shape. Credit: Mahr
Lens features have been getting too small to properly characterise – but metrology providers are catching up, finds Andy Extance
Keely Portway looks at some of the latest advances in light-based test and measurement techniques
Verifying the surface quality of optics has long relied on a visual, non-quantitative approach, finds Jessica Rowbury
Aspheres and other freeform optics are becoming more commonly used in areas like consumer electronics - but, as these lenses move further away from rotational symmetry, can the metrology equipment to test them cope? Tom Eddershaw finds out
