DOEMaster® Version 2018a Release Notes:

1/26/2018
  • New major features:
  1.  Further enhanced the quantization algorithm used for quantized DOE profile designs, especially for binary DOE profiles. With the new feature of “Binarize for maximum diffraction efficiency”, the diffraction efficiency of the binary Phase DOE can be very close to theoretical limit of 81%.
  2. Improved the wide angle beam splitter design algorithm.
  3. Added individual order control for beam splitter designs. With this new feature, it is easy to design spot arrays in which any spot can be turned off. It is even possible to accurately control the relative intensity of each spot.
  4. Added switchable English-Chinese Interface.
  • Major improved features:

1. A Chinese version of DOEMaster manual is added for Chinese customers.

  • Bug fixes

11/20/2017
  • New major features:
    1. Add Zernike polynomial based phase apodization for initial and optimized DOE profile for compensation of aberrations of real optical system used in SLM applications or any application that employs continuous DOE profile.
  • Major improved features:
    1. Re-implemented the DOE quantization algorithm so that the performance of the quantized DOE is greatly improved.
  • Bug fixes

DOEMaster® Version 2017b Release Notes

08/15/2017
