i am planning on building a 1200x900 100 watt laser and was wounding if the the beam expander/ red dot mount would work in this setup, what beam expander will fit this mount ( that lightobject sells) plus which size(power) should i get?
Thanks
Andrew

Re: Beam expander questions
Hi Andrew
Go with the 1,5x expander. For a reci tube the dot is already pretty big (~7mm), so expanding it to much (say 2,5) will require some pretty big mirrors. Remember that the beam will be "wider" than the laser diameter x expander, because they are at a 45 degree angle on the mirrors.
