Simon Lewis Posted January 30, 2015 Share Posted January 30, 2015 I've seen this laser unit advertised in L&SI a few times, and raised an eyebrow at the claims for audience scanning..."Intrinsic audience scanning safeguards are permanently calibrated by Lightwave International to ensure Phenoms are always audience safe at a minimum distance of thirty feet (9.1m). No operator, hardware, or software error can defeat the intrinsic safety design once rigged. Any Phenom rigged thirty feet (9.1m) or more from the audience will always perform under the FDA CDRH regulated maximum permissible exposure. "And...The Phenom is the first moving head laser to implement intrinsic audience scanning safety, making it the only pro-grade laser-effect device that lighting designers can use without restriction after rigging. Because of Phenom's audience scanning features there is no need to set safety zones or limit effects. Beam, aerial, graphic, and lighting effects can be achieved from a single fixture."Is this just a low powered trick or have they found a way of bending the laws of physics?http://www.lasershows.net/phenom/ Link to comment Share on other sites More sharing options...
peza2010 Posted January 30, 2015 Share Posted January 30, 2015 surely the only way they can be intrinsically safe, is for them to be so low powered they can do any damage? I think I'll stick to pangolin and ILDA for now. Link to comment Share on other sites More sharing options...
scjb Posted January 30, 2015 Share Posted January 30, 2015 surely the only way they can be intrinsically safe, is for them to be so low powered they can do any damage?Or have a suitable divergence... Link to comment Share on other sites More sharing options...
darossld Posted February 1, 2015 Share Posted February 1, 2015 Agreed, the beams look very chunky in the demo video so the unit probably has a large divergence that makes it safe at that range, however 9m still means that in a lot of venues there would still be a risk of audience exposure....

norty303 Posted February 2, 2015 Share Posted February 2, 2015 The whole point is that you don't rig it within 9m of the audience.the unit is of such a price you aren't going to be seeing them in your average local club anyway, run by DJs.If its in the US it'll still require a variance and therefore proper evaluation of deployment. My embolding... only pro-grade laser-effect device that lighting designers can use without restriction after rigging There's a thread on Photonlexicon that although alarmist and emotive (and at risk of going wildly off-topic!), does have some useful info from Lightwave towards the end...http://www.photonlexicon.com/forums/showthread.php/23543-Lightwave-International-and-their-questionable-Phenom-claims?highlight=phenom I think I'll stick to pangolin and ILDA for now. There's a good chance the lenses might be Safetyscan collaborations, PASS could be integrated and despite what they say, there is an ILDA port on the units. Is this just a low powered trick or have they found a way of bending the laws of physics? As was mentioned by the poster above, they incorporate a divergent lens system to reduce the power density. CCombined with a very fast scanfail system (Pangolin PASS??) they can get down to MPE at ranges you wouldn't normally expect, at the expense of some sharpness. I use lenses myself and can say from experience, I don't think think they had the lenses in place for the promotional video I saw. Link to comment Share on other sites More sharing options...

norty303 Posted February 2, 2015 Share Posted February 2, 2015 There's a lot of lampies there actually (including myself and Wookieboy at the end there) Their dislike is misplaced actually. A lot of the members there are US, so have to have variances and have had to jump through [costly] hoops to get them.So they are protective of anything that might suggest the purist 'laserist' role might not be required as it'll put them out of a job. You read a lot about 'but its all about the art', etc, etc but I don't toally agree. Equally, from a safety standpoint, once you know the issues/dangers, the thought of relatively untrained/unknowledgable folks taking over the task also worries people. On some level I'm inclined to agree, particularly based on some of the wild claims I've heard from 'so called' laser guys regarding what is safe/not safe.

dkumpula Posted February 6, 2015 Share Posted February 6, 2015 Wow, they really don't like lampies over there do they! :blink: As a long time member of that laserist community, I don't believe that is the general consensus. The most common complaints I've read over the years have to do with lack of coordination and communication between the LDs and the laserists for smaller gigs. In addition, as Norty points out, safety is foremost on the minds of (at least) the US professional laserists due in part to the federal and local safety regulations. That is not to say you can't harm someone's vision with a sharpie, but its significantly easier to damage someone's eye inadvertently with coherent light. Just my $0.02. -David Link to comment Share on other sites More sharing options...
