3D Non-Contact Surface Profiling has been extensively utilised to provide quantified images of material surfaces.

Recent work for a Swedish University has show the fine detail of a micro-lens array produced by a novel printing technique. The data showed that the printing method produced a uniform array.

Hole or Deposit

When a miniscule mark is discovered on a material it is important to understand if the mark is a deposit or a hole/scratch. Conventional microscopy often does not provide depth information but 3D Non-Contact Profiling rapidly provides the answer. This information can then be utilised to determine the route of further analysis.

A ceramics company have recently utilised 3D Non Contact Profiling to investigate a mark discovered after dishwashing a plate. The plate had a multi-layer glaze. It was shown as a hole and by measuring the depth f the hole the layer at which the failure had occurred was identified. The results lead to further investigations into the layer composition and it was determined that the glaze had not been applied correctly.
