PureMicro lasershow :-)

[RGB LASER VERKOOP]

i use safty zones as th emost in europe, not see the new lenses in practise...
problem is people want a tight beam, and when use this lenz you making a flash light again....
i see it at the lem party, but i chose for safty zones for get safe lowe power beams that go to people...

as the must is going in the sky
and my video's look powerfull, but it was perfect smoky and dark.. when other lights go on, than the visible power is almost gone
see: Attachment 31713
this is 6W RGB, 2,3W RGB lasersystems and 1,6W Kvants, now almost no visual. but in perfect condition, it is verry bright!

so just not pick on me becourse a video or a picture please, ask for the facts!

[norty303]

Ok, facts.

What power was used in the zones and how far was the crowd in the first video we've been talking about?

[RGB LASER VERKOOP]

10% from 1200mW
distance to first people about 10meters...

only problem is i not messure the 10% power, but for my feeling was low and safe...
i will learn from this that i bring my power meter next time :-)

[norty303]

So the beams we can see in the crowd were 120mW? (or thereabouts) and the overhead were at full power?

Dear Joost,

do you really think we believe the lower part is set to 10% of the power while there is no visible difference in the video?

There could be 3 scanarios.
1. you are lying
2. The safety zone in Phoenix is broken
3. the pure micros doesn't modulate.

But lets give you the benefits of the doubts and non of the 3 scenarios are right, and you used a superduper camera which cannot tell the difference between 120mW and 1200mW. Even then you are scanning above MPE, ok at 1ms exposure maybe only 8x but still.

Ok now pay attention!

Did you know you 9W 1,5mRad @ 25 meter is more safe than your 1200mW 1 mRad @ 10 meter!

example 2, a 40W! green laser wit 2 mrad at 40 meters is more safe than your 1200mW pure micros at 10 meters

Note all above examples exceed the MPE by allot and are not safe.


DISTANCE IS EVERYTHING!

10 meter is NOT a acceptabele distance for powerfull lasers

PS. I (we) have seen your shows in real live.... but because you clients aremight be watching this forum I will not comment on this....

Oh did I mentioned DISTANCE is everything?

[RGB LASER VERKOOP]

thanks !
when see my show, come say hello ;-)

[White-Light]

I would happily show you Pangolin Safety Lenses but I haven't got any yet. Something for me to buy later this year.

However, there is a video here of the safety lenses in action at PLS:

My 2 cents :

I did a few shows with a proper BAM to respect the MPE (well, 18us MPE so 28mW/cm^2), with 3W and 4W RGB (between 1 and 2 mrad), and first audience impact was 15 meters from projectors, so BAM was between 3% and 10% at 15m (if I remember).
But I fastly realized it was not worth AT ALL doing MPE legal shows, as beams was just not visible at all in the first BAM zone. So I simply ended up not doing audience scanning in small clubs!

Until I discovered lenses and increased divergence to 8-9 mrad

So if beams appears bright in the 10 meters range into audience, the lasers either are way too powerful, either there is lenses at the aperture...

[RGB LASER VERKOOP]

I think for the mpe was to high in this show... as a good mpe safe show is almost not visible...
I think the lens is a good option, but then clients need to install it correct!

i was at this show in pro light frankfurt, but i not see the show.. pangolin had a small booth with some kvant lasers.
My interest that short day with so much to see, was on other products.

I will in the future put less power in the low zone... and most beams above the people.
special in small clubs.

thanks for all tips
maybe someone can make a nice list with laser power and meters for safty mpe.
like 1W green and 2W RGB etc....about 1,2-1,5mrad as the most will be...

i try download app on my phone, but for android not have it pitty!

@ sbk,

I agree shows below mpe are useless, most shows in europe are above mpe, BUT there is big difference by exceeding the mpe by a bit (lets say 1w, 1,5mrad at 20 meters) or exceeding the mpe by allot ( lets say 1200mw 1mrad at 10 meters)

@ whitelight, i allready showed the lensed to joost last year at the lem, and i even sold them for 10 euro 3 years ago at a lem! I think i sold one!!! people are only intersted in power and low divergence.

@ joost, did i mentioned distance is important? We have a show in a small club next thursday, we will be using lenses. I will make some video for you.
