I checked the CVI lens we should buy if we want to replace the thorlabs lens now we are using between OPO and homodyne.

The result is attached in the figure. Since we could find a lens with the focal length similar to thorlabs focal length, the simulation result is similar to the previous simulation. In this case, the lens we should buy from CVI is PLCX-25.4-46.4-UV and PLCX-25.4-70-UV.

Also if we have again almost 100% match from OPO to AMC, the telescope design for filter cavity injection should be not be influenced.
