ZEMAX Relay lens system

[takio]

Hello

I hope to transmit the image that is created by the fish eye lens to a sensor, using two aspheric lenses.
I don't have much experience on ZEMAX, but I worked on the simulation for the application.

1) Fish eye lens (E1628KRY)
Focal length : 1.65mm, IMGC 5.38mm
2) Aspheric Lens (Link)
EFL : 50mm
Diameter : 25mm
3) Sensor : 1/4"
Link

The set-up for the relay lens system is

IMGC - (50mm) - Aspheric lens - (100mm) - Aspheric lens - (50mm) - Sensor.
*IMGC is the image that's created by the fish eye lens.

And I used ZEMAX, I got the optimized distances as below.

For my application, I just used entrance pupil diameter,, but
I noticed that there are several aperture types.. for the simulation for my application,, what is the proper aperture type that I need to use?
I saw the image quality changes,, according to the aperture types.

I attached the relay lens system file as well.

Thank you
