I have a BEC 50 watt fiber that I have 2 lens' that I got when I ordered with the laser. The lens that was installed on the fiber when I received it was the 110mm, I have the need to install the 300mm lens for a job that I have coming in a few days. If I understand what I am looking at I think that both lens' have the same focal length, am I correct? And what is the best way to set up my computer so that I can use both lens' ? Should I install EZCad2 with another name for the new lens?
Thanks
Terry Wade
