I have a ~200mW 650nm laser and eagle pair 190-470, 610-760nm OD4+ safety goggles. How should I go about viewing the beam? Is there e a safe set up for viewing the beam without goggles?

a camera. Or you can go outside, mount it to something and then view the beam. Just dont aim it too close and stare at the dot.

What about with goggles on? Would I need an insane amount of fog?

im not sure, I dont own a 650nm laser yet. Sorry i noticed you do have goggles. To view it outside just point it at the sky, making sure no aircrafts are around. Then lower your goggles for a few seconds. Just be safe and you should be fine. Dont do this if other people are outside though. If you drop your laser it could hurt someones eyes.

If you can see the beam with goggles on they're probably affording you zero protection. I would make sure your laser is well secured, check the conditions using a camera, and then sneak a peak.

I already read that, Sigurthr. What I meant is is there any way to view the beam WITH goggles on?

I always have no goggles on while in the house and what I usually do is point the laser on the carpet or wall for like 3-5 seconds and turn mine off.

Just use no goggles. (Provided your shining it on something that won't reflect)

Good goggles won't let you see even a 2W beam with so much fog that you cannot see your hand in front of your face.

dont mean to threadjack, but i want to get some eagle pair goggles the same as soren (190-470 + 610-760) but on survival lasers all i could find was 190-470 660-760. will these ones protect against 638 etc?

daawood123, the rolloff begins at 610nm, so yes, they will protect you.

Soren, to view the beam, just take the goggles off. Simple. The point of the goggles is to prevent a direct hit from the beam being harmful (hence OD4 attenuation -- every mW is reduced by a factor of 10^4).

You don't need goggles every passing second. Although 200mW is nowhere near eye-safe, when properly controlled, it's not such a big deal.

Exercise common sense and don't point it in the direction of anything potentially reflective, including windows, mirrors, retroreflective signs or still water.

Don't stare at the spot - a quick glance or two even at the beam termination spot from a fair (>1m) distance away is fine, though.

Why all this crap about beam view goggles , buy a 5 mw green or red why spend 50 bux on a pointer and use goggles so you can't see anything
200 mw red is not dangerous to look @ the beam with a lil fog , just avoid reflections those are nasty

+ do not put the laser on a surface were it can roll easily!
A sturdy tripod is a must, when observing the beam from a distance.

Always good to bring a camera to see what the conditions are before taking off the goggles. Plus you'll want to take pictures too right?
