Optimise with reduced aperture for only one of several wavelength

If I have a broadband sequential imaging lens design with 100mm aperture but one wavelength only is delivered via a beam-splitter of smaller diameter (~40mm) placed in front of the lens,  how do I set this up to optimise without actually having to include the beam-splitter in front?  Can I put some kind of zero thickness mask in front which retricts the diameter of the one wavelength only but is invisible to the rest?

Sorry! Zoom is the word. In the MCE, zoom the weights of the wavelengths.

I’d use the multi-config editor to soon wavelength weights and aperture

Thanks Mark,

I was wondering if the MCE was the way to go, so now encouraged by your reply.

One thing though, I think there is a typo there: ‘… editor to soon wavelength weights ...’.  Trying to work out what it should be.
