![]() Zemax unit (radians) = ZYGO measurement unit (mm) x 2 PI / 0.0006328 = 9924 x (ZYGO measurement unit) In the data file provided by this example, the measured wavelength is 632.8nm, then: ![]() ![]() Zemax unit (radian) = ZYGO measurement unit (mm) x 2 It should be noted that if the measured data is stored as wavefront data, we need to treat this data file as phase data.The Grid Sag of OpticStudio is in radians.Therefore, the measurement data need to be converted, and the conversion formula is as follows: The screenshot at the beginning of the data file shows that the data format is the same as the Grid Sag data format mentioned in last week's article.The number of data points in XY direction is 732, and since the distance between data points is 0.01344, the diameter of the data file is 9.72mm.Where the first line of the file has a terminal flag (flag) of 0, representing the data unit of mm. DAT file, and to save the file in Zemax root directory "DocumentZemax/ObjectsGrid Files". ![]() ZXGRD file, we need in OpticStudio converts the file format. We use ZYGO interferometer provide data as example, ZYGO interferometer generated data file format for company. In this case we use ZYGO interferometer provide data as example, ZYGO interferometer generated data file format for company.
