Hi Zemax Community,

Can you help me with this?  I have read the passage

https://support.zemax.com/hc/ja/articles/1500005580162-%E5%85%A5%E9%96%80%E3%82%AC%E3%82%A4%E3%83%89-1-4-%E6%AD%A3%E8%A6%8F%E5%8C%96%E5%BA%A7%E6%A8%99%E7%B3%BB

 

and want to confirm that my understanding is right. 

Things want to do

To trace the specified field & wavelength light ray location on the image surface.
   here are wave1 and wave2 at field1 (my model is a spectrometer)
 
I use REAY in merit function and set the wave1 and wave2 coordinate as below

 but I am not sure whether it is right , could you please help me see it ?

 

Thanks 

 

Yang

 

 

Hi @Yang.Yongtao 

Open the field data editor and define your fields there:

Hx, Hy are normalized definitions.

So when x=0.5 in the object plane → Hx=1

When y=0.5 in the object plane → Hy=1

 

You can then check this with the Single Ray Trace:
