This video shows test of two laser optics' setups of my Inova SLS 3D Printer.
First setup includes anamorphic prism pair to correct shape and size of the laser beam and the plano-convex lens to focus it. Second one consists of fast axis correction lens embed in laser diode and Keplerian telescope to extend the beam size and to focus it
Initially it was not intended to share this video - I made it from my working video-notes. I am sorry for its the quality.
