Would I need goggles for a 110mW BR if I'm safe and dont burn things with it.
Is it safe to look at the dot on dark non reflective surfaces outside?
If there necessary, where Can I get cheap goggles for BR

Do you have a very strong willpower?

To me, owning a high powered laser and not burning things seems like owning a gun and a range without ever shooting it. But that's just my opinion. thesk8nmidget has some great BR-specific goggles for sale, $35 each. I ordered 2 pairs, and they work great. You can find the thread in the Group Buy category, and a link is also in thesk8nmidget's signature.

I would highly recommend buying goggles. It is safe to look at dark non-reflective surfaces outside (not too close up), but goggles allow you to see optical effects, burn things safely, see fluorescence, and many more. Fluorescence can open up a whole new world; you will be surprised by how many things you can see fluoresce when you are wearing goggles!

I agree with rocketparrolet, unless you don't have any desire to burn things. You could pop balloons by covering up your eyesand aiming torwards the balloon. Chances are you'll hit it. :D And no one can resist not writing on glow in the dark stuff. ;D

But still, those only protect 400nm-532nm. Blu-ray laser tend to have wavelengths of 395nm-415nm. What if your laser happens to be under 400nm? The DL goggles are rated for protection against 190-500nm.

Thanks for the reply.
Could you tell me the name of the model that works against blu ray and where you bought it?

Thanks again

My dragon goggles for green, also seem to work for BR. The spot from my 130mw Blu Ray becomes almost invisible when shone on my laserbee sensor.

Would I be fine with those:

I'm assembling a Dorcy Jr. Mod, using a PHR-803T (80mA).

Thank you for your help

You should be really careful about not using laser goggles. Laser goggles are specially coated for protection against concentrated light beams. They reflect and absorb most of the light. But using protection that is not rated for protection against laser beams can be taking a HUGE risk. If it is not made for relfecting lasers, it will bleach quicker under laser light. Even if only a small amount of gets through, it only takes about 6mW to do eye damage. If you get hit in the same spot twice, it would definately do damage. Even if you get hit for half a second, that's more than enough time to bleach the glass and get a direct hit in the eye. Blu-ray is much less visable than red or green (about 12x), so even if the dot looks weak, it could be a lot more than 10mW. Even indirect exposure to a laser dot at high powers could cause damage.

I just hope that you know what a huge risk this is, and you'll be extremely careful with it. If you ask my oppinion, my eyes are worth the extra money.
