Laser projector power selection

How to get PASS

For use within the United States, LSDI sells a series of laser projectors that already include PASS and for which a CDRH variance has already been approved. Contact LSDI for more information about their CONEX laser projectors. For use outside the United States, contact Pangolin for more information.

Not sure if this means PASS is only available in the USA through LSDI or not...?

I also see this "Easy to install in any projector" . That leads me to believe it can be purchased and added to any projector. But using it does not mean your projector will automatically be safe for audience scanning use.

Exactly right. As standard practice one should be configuring the projector (position, throw, beam blocks, BAM, scanfail zones/PASS settings), show and software for each installation.

One thing that concerns me here is that the web site for Xtreme doesn't appear to mention that even with PASS you still need to take measurements and set the projector up properly 1st, at least that's my understanding of PASS. I understand you set up the projector take the measurements and then set those measurements as a maximum level within the PASS system which then prevents that maximum being exceeded. However, it needs you to set that maximum 1st. The web very much gives the impression to me that you can simply buy the projector, throw it up in a club and it will be safe. I'm sure they tell enquiring clients that but it would be better to mention it up front.

I read it differently. I read it that they have to install and configure it for you. Which totally makes sense. Its the only way they can confirm you are meeting all the guidelines.

I dont think they offer their projectors to "mobile" laserist like myself. But thats OK. I probably cant justify the cost even if they did.

Its just cool to know that it is possible.

Tha PASS hardware itself isn't all that expensive. Bill talked about it at one of the FLEM's a while back, and if memory serves, it only adds around $750 to the cost of the projector. Where all the extra money comes in is in all the other integration that goes with it, plus the paperwork, plus their attempt to recoup their development costs (and the close to 2 year delay they incurred while trying to get CDRH approval for the thing).

PASS is only available through LSDI, and I believe it's currently only available as an installed option on one of their in-house projector designs. Bill once mentioned that they *COULD* sell the board by itself, in theory at least, but without all the integration knowledge you'd probably never get it working 100% reliably, which sort of defeats the purpose. You can give Greg Makhov a call over at LSDI if you're interested in more info though.

What are the options for other scanfail hardware to satisfy the CDRH requirements (not crowd scanning).

I have searched on the board and found a few things...but what are the current recomendations for plain scanfail hardware?

If you aren't crowd scanning, the best bang for buck scanfail solution is a roll of Blacktak (aluminium tape to me and you) that you use to physically mask the hazardous areas.
I paid £15 for my roll but it'll last for ages.

You don't need to overcomplicate the solution with fancy electronics.

From what I understand... you have to have scanfail protection if you want to get a projector varianced in the USA.

[norty303]

Physical masking IS scanfail in as much as in the event of a scanner failure, it prevents dangerous emmissions entering an audience/hazard area.
Just because someone makes a board to do it electronically, doesn't mean to say its the only way of doing it.
