The aspherization of Fizeau interferometry

With ultra-precise objectives, asphericon extends its product range to the area of metrology and redefines Fizeau interferometry. Discover the world-wide only aspheric Fizeau lens a|FizeriC.

In addition to reduction of the number of lenses used, the use of a high-end asphere increases the measuring range. The a|FizeriC 4 ” not only expands the spectrum of measurable test specimens, for the first time it allows a 4” Fizeau lens to cover the measuring range, which previously could only be measured with a 6” lens.
