Fizeau interferometer measures transparent surfaces down to 0.2 mm thick
The AccuFiz Duo dynamic interferometer combines patented AccuFiz D short coherence capabilities with long coherence capabilities into a single system. It enables surface error, transmitted wavefront error, remote cavity, wedge, optical thickness, and homogeneity measurements of plane parallel transparent surfaces down to 0.2 mm thick.
