Wow, sorry to say this, but what a mess. Pat is right, there is not much that is legal about that laser. I certainly wouldn’t describe it as ‘A fully converted for laser show use working Laserscope Orion in excellent condition !’
It would be pretty much illegal to use the system in that condition indoors or outdoors here in the UK too. And in doing so would definitely invalidate any public or employer insurance.
Sorry to sound harsh, and it’s not a personal attack on you, but it’s bad news when high power devices like this, which don’t conform to any Laser Safety Standards turn up on the marketplace. Particularly when they are being sold as an ‘excellent condition converted system’.
Hopefully someone on here will be able to make Simon an offer for the laser as parts, and rebuild it into something that is semi-safe.
