We have been using a Leybold L560 for last 13 years with Turbo pump without any problem. We are thinking of buying a used machine with diffusion pump. Can anyone tell me if this will give good results with Single Layer coatings as well as multi-layers, with regard to durability. We have never used diffusion pumps before and are not sure about their use in the precision optics industry.
Thanks
