Would a beam be visible with a pair of laser safety glasses which have a high visible light transmission? for example the Eagle Pair® 190-540nm Standard Laser Safety Goggles (

I doubt it, but if you are interested in viewing the beam consider this - almost no one here uses goggles 100% of the time. There are situations that most members consider acceptable to drop the goggles for temporary use.
For example, if you are in a safe situation outdoors at night. Beam viewing is what that is all about! So you don't wear
googles, (edit - GOOGLES - I crack myself up!) but you are VERY CAUTIOUS to make sure that...
A. No laser beams in flight paths;
B. No laser beams that could shine in anyone's eyes short of NOHD (which should be generously calculated with lots of headroom.)
C. Extreme caution regarding accidents like dropping the laser or having it fall from a mount or tailstand.
Basically, if you are shining a high power laser at night, outdoors and using GOOD common sense, it is considered (by many) acceptable to use the laser without goggles. Viewing the beam outdoors at night is one of the more rewarding aspects of laser pointers for many of us.
Now if you are indoors, a laser of that power is going to require goggles. I know some on here have used them without goggles, but it is pretty much a huge gamble at that point. If you catch the wrong reflection off of something that is not matte, you can easily damage your eyes in fractions of a second.
You will still be able to see the dot indoors with goggles. So you would use the goggles for things like burning or popping balloons, etc... Goggles actually help you focus the laser as well. It is almost impossible to stare at the dot on a wall at those powers, but with goggles you can look and see much more clearly as to whether you are focused tightly.
I hope that helps. If I am overlooking something, please anyone feel free to step in - I'm thick skinned and I'd rather have correct info than worry about whether I am right or wrong.
THAT SAID, I know some people may take a more cautious stance than me - so I will add that those are the precautions that I TAKE and they may, or may not be the same as you want to take. :beer:
