Determination of Flange Focus Distance and Aberrations
With the ELCOMAT®wave, the focus position can now be determined with up to four apertures instead of two, as with the Mark III 45S camera tester. This extends the test spectrum from one-dimensional to multi-dimensional focus position determination. This means that astigmatism and coma of isotropic lenses as a result of misalignment and decentration can now be qualitatively recorded, documented and, if necessary, corrected using the four apertures. Furthermore, anamorphic lenses can be checked for astigmatism and coma - an important aspect in service and testing. With the LED illumination of the ELCOMAT®wave, chromatic aberrations in red, green, blue and white can also be analysed.
