Hobbyists like to mess around and combine 2 diodes for ~7watts I gave up on pointers and went the whole hog and built my own red/green/blue scanning projector doing graphics and beam shows using Pangolin software. Lasers still fascinate me While burning stuff I noticed every once and a while the camera would get a bright narrow vertical line flash across the middle of the video, I'm assuming that without proper eye protection that was potentially dangerous reflected laser light hitting the camera lens ?

Accutronitis Posted December 30, 2016 Author Report Share Posted December 30, 2016 (edited) I just bought a new 1 Piece Laser Collimation Glass lens, The transparence ratio of the normal collimation lens of the market is around 70-80% due to the long focus distance. The one I just bought has a Transparence of 98% and it just cost $8 ! The original laser diode's light is difused a long focus lens will bring more power lost. The normal collimation lens's focus is 7-8mm but this lens' focus is around 2.357mm. So,the power lost will be the less and the beam effect is the best ! I love a good upgrade !
