Hi all, In the tolerance wizard the surface irregularity is given by no. of fringes. Some vendors of lens give the surface irregularity in unit of RMS Angstrom. Is there any conversion factor between these two units? If not, is there any other way to overcome this disparnecy? Thanks a lot, Nadav
Hi all, Is there a simple way to do a reflection grating in NSQ mode?Thanks,Nadav
Hi, Is there a way to use UDA while also keeping the required mechanical diameter? I have a lens like this:And I want to increase the mechanical diameter (red) and then cut the lens like that(second image below): right now by using the UDA I got this:Hope it is clear enough. Thanks,Nadav
Hi all, I am trying to export the lens in the attached file to cad file(step).I got an error for surface no. 4 -failed to export.When increasing the clear diameter of the surface to be the same as the mechanical diameter, there is no problem. Thanks,Nadav
Hi all, Can coating like beam splitter be defined in mixed mode? I try to define them like in full NS mode but didn't see any effect. Thanks, Nadav
Hi all, Is there a way to do tolerance analysis to diffractive surface(binary 2)? Thanks
Hi all, During tolerancing of some lenses (using the mtf as criteria) I get the “Lens cannot be traced, tolerances may be too loose!”However, opening one of this the monte carlo files it seems like the mtf is bad but larger than zero. What can be the reason for this? Thanks,Nadav
