I want to give a customer access to a Zemax model, while hiding our proprietary optimizations. I have previously used the Black Box feature to do this with no issues, with other clients and with similar models.
The customer does not have access to Optics Studio 20, so I downgraded my installation to version 16 and created the black box. The file that Zemax generates to hold the black box gives the error 'Pupil Ray TIR' and will not update. The model only has reflective optics, so there is no refraction at all. I was able to successfully create the black box and open it in Optics Studio 20, but this will not work for the client.
Are there any suggestions for solving this problem?
