However, beam propagation and the options for setting up propagation analysis is a fairly complex subject, which has been documented in our Computing the size and location of a Physical Optics beam on a surface is a very frequent requirement. This makes it easy to improve the accuracy of fiber and waveguide coupler designs using Physical Optics in OpticStudio by providing more accurate input data. Here is some key points for taking back: The ray-tracing eqaution for grating While diffractive optical elements can be modeled in both Sequential and Non-Sequential Mode in OpticStudio, Non-Sequential Mode's ray splitting capabilities can be quite The array size does change duing the beam propagation, expecially when you propagate from inside the Rayleigh range to outside the Rayleigh range. The objective is to design a microlens focusing a uniform beam of 250um diameter into our PM630 fiber Hi Rui, If your system has tilted cylindrical elements, it is likely to fall in the category of generally astigmatic systems, and if those cylindrical elements are not aligned with OpticStudio does have physical optic capacilities. A dummy surface may be used as Physical Optics Propagation (POP) - API settings · MyZemax Please note that the POP analysis was added to the API in the OpticStudio 20. Before you can use this data, make sure to save the settings of your POP Fast beams tend to be accurate enough with Geometric optics so that diffraction effects are minimized. It models Gaussian beam and reports various beam data, including beam size and waist location as it propagates through a paraxial optical Hi everyone, I find that one of the most useful tools in OpticStudio is the Physical Optics Propagation tool.
