Thanks everyone!
Hi Grainde, in the first three pics here is what I used:
First - 650nm 200 mw & 638nm 130mw through Dragon Lasers Fan Diffraction gratings
460nm 100mw through an Optotronincs Gel Star Diffraction grating
532nm 100mw into mirrors
Second - 650nm 200mw & 638nm 130mw through Dragon Lasers Fan Diffraction Gratings
Two 405nm 500 mw using Lasesbtb Circle Diffraction caps
589nm 5mw through an Optotronics Gel Star diffraction gratings
Third - 589nm 5mw through Dragon Lasers Diffraction Fan Grating
532nm 100mw though Dragon Lasers Diffraction Fan Grating
532nm 80 mw through Dragon Laser Diffraction Fan Grating
405nm 500mw using Laserbtb Circle Diffraction Cap
650nm 200mw & 638nm 130mw into mirrors
A while ago I purchased an Optotronics Lens kit and it came with 2 star and 2 beam splitter gel (very thin plastic) 2" square gratings. I really never used them because in their present form they were very awkward to use. Last week I got the idea to take 4 very old 35mm slides and cut out the film and cut the gratings down to size and tape them to the back of the cardboard slides. In that format I have found they are very useable and give me four more gratings, though not nearly as good as the Dragon Laser ones, but they are nice. One thing I do like about the Optotronics Star ones are they do not create as many beams as the DL ones, or for that matter the Lasesbtb Star caps and do not overtake the picture.
