In the video, Dan talks about setting the light up at about head level, and then raising it once it is positioned and necessary beam blockers are in place. Changing the height also changes where the beams go. How do you set up the beam blockers so they will be properly positioned when raised? (Especially if you are going to mount it on a flying truss for a weekend) Thanks.
Well, simply put a slot would be made as part of the case and thus be rigid. Beam block foil is very flexible and can be cut to fit any need. We often will bend and/or score it to make a custom block for a unique situation which would be impossible with a rigid frame. Club laser systems can often get away with a metal block but we made this with mobile use in mind. Better to have more flexibility than less.
I have 2 question: 1. Can 3b or IV lasers physically hurt people other than their eyes(i.e. hands and legs)? and 2. Do these safety rules, like Beam Blocking, apply to 3a or 3R lasers? I noticed you guys were generally talking about the more powerful lasers, but I'm just concerned about getting in trouble with the less harmful ones. Thanks!
1) Yes but mainly skin reactions only occur in class IV lasers. Class IIIB is just not strong enough GENERALLY but there are a lot of variables. Lots of IR from cheap laser diodes will burn you.
2) Beam blocks are only required in IIIB and IV but generally are a good practice in all lasers. They are quick and easy to use so why not just do it?
wel the only thing i got with the laser was a power cord a plug for the panick butten and 2 keys for turn laser on off i have the g-20 from a company kald lightmaxx
That does not sound like an approach that would be FDA compliant. But, if you are in Holland you are under the IEC guidelines and I honestly have no idea what would be said about those.
I thought Dan had told me that 3 meters above the tallest person's head would keep them from reachching up and making contact with it. I may have gotten it wrong. It was a long week
The 3M rule is to create a "safe" zone that acts as a buffer between people and the lasers. Thus the FDA wants high powered laser beams kept 3m in lateral and vertical separation from what they call "human exposure." However that rule does allow some flexibility under various show circumstances.
Yep, ur right. 3m from the floor would only be 9 feet which would create maybe a 3 foot buffer which is not much as all considering that a 1mm movement of the mirror could cover 3ft easily at a distance of maybe 20ft. The rule is 3m AWAY from people, above, below, or left/right. Again though, there is some flexibility there for those of you with a 15 ft. ceiling or whatever. Class IV is strictly 3m for safety sake.
Probably not, but what you NEED to worry about in this sue happy world of ours is "perceived" damage. Someone may claim they have eye damage and if you were shining the laser on the crowd, there may not be a legal leg for you to stand on.
so the people we see on youtube using these in there house pointed at them are getting Radiation poisoning ?

thank you brian and dan for the help greatings DJ mike from venlo holland
ljmike1204 3 years ago
wel all i got was a plug i welded a switch on it with standerd spearer wire and 2 xlr plug so i can use the multy snake if i hang it on stage
ljmike1204 3 years ago
Not sure if that's good enough to be compliant. Dan would know and I'm sure he'll chime in soon

so we can let the laser shine on the ground? but... can that still get in peoples eyes?

It needs to be at least 3 meters from the tallest person in the room's head

Right on, but 3 meters from where? Joe thinks it's the floor and I'm thinking you told me it was above the tallest person's head in the room.

ehm wel i have the panick butten so i can turn off the laser it self but how longe can i make the butten wire ??
