Dear Experts

I have calculated two end coordinate points of an off-axis parabolic mirror lets say (184, 13.5) and (217, 18.8), may i ask if i can design this mirror in zemax by using these coordinate points and focal length of 200 micron.  Please advise

 

All units are in micrometer.

Hi Saif,

There are two way that can be used to make Off axis mirrors!

  1. You can define the aperture (rectangular, circular etc.) and off axis distance from surface setting tab under aperture section. Off axis distance will decide the offset from center of parent mirror and defined aperture will decide the size (geometry) of OAP.
  2. If you have complex geometry (Hexagon etc.), you can define a "User defined aperture" based on your coordinate points and apply the defined aperture to parent mirror.

Hope this helps!

Thanks.
