Simulation in ZEMAX

• make values in ZEMAX model those for Build 1 design - replicate
• spot size vs wavelength and x-axis. enclosed energy, resolution obtained
• MTF of total system. Not enough to comment on SNR - stray light, e.g.
• tolerance analysis - tilts and decenters, ignore clocking, resolution obtained.

Room for exploration:

• see if we can improve by making aspheric achromat
• relays with magnification and shorter focal length objective lens
• Reducing f/# and observing effect on signal brightness in ZEMAX
