Will one of the DVD LDs have a visible red beam?
yep i have to do that usually to see the <5mW 635nm's beam. it's impressive for a <5mW red to do that thoughDeath Angel said:I know a sony 16x laser diode is visible in the night sky. But not like a green though. If you look eye level with the laser away from you then you can see the beam.
