一、DOEMaster®Diffractive optical design software
DOEMaster software is user-friendly, operation profile, full Chinese technical support.
DOEMaster can design a variety of diffractive optics such as beam splitters, diffusers, shapers, and more. Diffractive beam splitters allow one laser beam to be split into beam arrays, or multiple lasers can be copied into arrays. Diffraction diffusers enable arbitrary 2D light patterns to be designed according to the determined scattering. Diffusers and beam splitters can be used to transform coherent and partially coherent light sources. Diffractive beam shaping can combine coherent laser beams into rings, rectangular top hats, linear patterns, or custom 2D intensity distributions.

- Standard 64-bit software, fast and efficient multi-thread optimization, DOE design for any challenge, diffraction angle up to 120°;
- Easily implement large DOE to 10000×10000 sampling pixels;
- Based on the latest iterative Fourier transform algorithm (IFTA) optimization method, fast convergence achieves high efficiency and high uniformity of diffraction images.
- More initial phase selection for fast and optimal optimization results;
Intuitive and smooth workflow, when any design parameters change, the entire system - automatically samples, immediately updated, to achieve accurate and rapid optimization;
- Professional graphical display interface for easy system evaluation.
(DOE images designed with DOEMaster contain 120 large angles of diffraction)
A variety of conventional or diffracted beam splitters, diffusers, and shapers can be designed. Diffractive beam splitters allow a laser beam to be split into beam arrays. Diffraction diffusers enable determined scattered light to enter any 2D light pattern. Diffusers and beam splitters can be used to convert coherent and partially coherent light sources. Diffraction and refractive beam shaping can combine coherent laser beams into rings, rectangular top hats, linear patterns, or custom 2D intensity distributions.

二、GratingMaster®Software
The software has an intuitive visual interface for designing a variety of grating structures: square wave holographic gratings, shining gratings, sinusoidal, trapezoidal, triangular, three-point polyline and many other structural gratings. Contains diffraction gratings, structures, diffractive optics, photovoltaic systems and spectral gratings. The characteristic size of the grating can range from nanometers to millimeters. Diffraction efficiency, near field, polarization, reflection, transmission, and internal field can also be calculated. Holographic grating, Bragg grating, surface grating, photonic crystals, diffractive beam splitters, polarizers, anti-reflective custom features allow users to analyze and optimize user-defined structures of the grating. These include importing measured height profiles as well as programmable height profiles or refractive index distribution media that describe a height profile using formulas.
