a|FizeriC - 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.
Besides the outstanding quality of the Fizeau surfaces, which are available with both λ/10 and λ/20, the a|FizeriC impresses with an innovative design. Thanks to a self-developed packaging and storage concept, all lenses of the product family can be easily removed and used quickly.
The superiority and extended application range of an aspheric Fizeau lens can be seen in a direct comparison with a spherical lens. Both Fizeau lenses have a 4'' input beam diameter, which leads to a limited measurement range for spherical designs. Whereas the a|FizeriC widens intrinsically and thus, achieves a larger aperture diameter.
