OD4 or OD5?

[Protoless]

Should I get these goggles (OD5) or these goggles (OD4)?

Would I be able to see a 40mW 532nm laser through the OD5 goggles or should I get the OD4 to be able to see it better?

Thanks!

For only 40mw you are going to have a hard time seeing the dot with either, it will be very faint.

Also you are aware you will not be able to see the beam with any glasses on right? so if you want to do some beam viewing you will need to construct some kind of a beamstop to hide the dot from view while you look at the beam. Or if outdoors just shine the laser on a non reflective far away object and you will be ok no googles.

I'm planning on using the goggles when setting up the laser to burn things indoors, but I need to know if I will be able to see the laser dot. I can use it without goggles if I need to see the beam when I'm outside, so the beam isn't a problem.

OD4 is fine for anything you're likely to use. If I recall correctly, anything up to 10W is reduced to 5 or less mW.

Both of those goggles have a very poor VLT rating at only 20%, unless your living room is lit by floodlights the scene will look quite dark. I would get the orange eagle pair which block 532 and have far far better VLT. This is of course on the assumption that the laser isn't emitting godly mounts of IR. Still, I'd consider the enhanced trip factor from not being able to see properly to be a worse risk.

It has no IR filter, so it's probably emitting 40mW+ of IR. Is 20% VLT a problem or can I still see the laser and things around me in a normally lit room?

In a well lit room yes, in a dark room no.
