Expand green to match larger beams using telescope.
Hi.
With cylindrical lenses?
Thank you.
Sorry.
Where I can buy a telescope to expand the beam 5mm, for Nichia NDG 700mw/520nM with G2 lens?
Thank you.
make your self. Buy two plano convex lens such that the ratio of the focus length of each lens is the ration of the magnification you want. For example a 2x could be a 100mm and a 50mm lens a 3x could be 100mm and a 33mm etc.... The distance between the lens is the sum of the lens fl. for example the 2x would be 150mm long. You can do 10mm and 5mm and get the same result for a 2x (thanks planters
There was a place I use to buy them for like 20.00 but I can't remember the name of the place.
