I would lean toward more dangerous, the fact that they are nearly invisible means your eyes will be far more dilated and you'll likely have no blink response if a beam hits your eye. Your retinas will be wide open to injury and you wont notice it until you feel it.

Re: Blu-ray / 405nm UV Fluorescence & Glow Kit (updated 6/15) Yes, I have one more in stock and then I'll be out until Thursday. You can PM me your paypal email if you'd like to purchase one and I can send you an invoice.

Nice deal you got, is there any indication who the manufacturer was?

Really admirable of Lasever taking the initiative to replace your laser, and good review :beer:

It's recommended (especially for high value items) that you post at least one picture with your LPF name + date written on a piece of paper to show that it's actually in your possession. Good luck with the sale though :)

Re: Blu-ray / 405nm UV Fluorescence & Glow Kit (updated 6/15) All orders as of this post have been shipped! Glad everything got you safely, I'm looking forward to seeing pictures :D

These stats are pretty nonsensical, I'm not sure how reliable the mW rating could be with a description like that. Either way like others have said, if used properly they can be very safe. Just make sure you educate yourself and learn the right way to use them.

Lower wavelength light is higher energy, that's why you'll notice lower wavelength lasers burn more efficiently than higher wavelength counterparts of the same mW rating (in most cases). This thread should also help you a bit...

Your eyes are the biggest concern, make sure your goggles are performing as well as advertised (many cheap ones do not). Pass the beam through a corner of one of the lenses and it should be about as dim as a cheap $3 red pointer on the other side. Make sure you're always aware of anyone else...

Re: Blu-ray / 405nm UV Fluorescence & Glow Kit (updated 6/15) Glad you like it! I hope you and your niece have fun experimenting, just don't forget the safety glasses :wave:

Re: SALE: $100 PT-30Kpps High Speed Galvos, work great! I've seen this video many times in the past and always admired your setup :D I think I've even left comments on a few of those videos before. Small world, eh? RRGB Multicolor Laser Show Projector - YouTube Kinda cool to own a part of...

Re: SALE: $100 PT-30Kpps High Speed Galvos, work great! I'll take them, message me to work out payment and shipping to California? :) Do you have any pictures of them scanning ilda test frames or anything? Your post said pictures were attached but I did not see any.

Re: FS: Polarized Beam Splitter Cube A PBS cube can be used to combine 2 lasers based on polarization instead of wavelength. This means you can combine 2 lasers of the same wavelength (which you cannot do with dichros) by having one of them rotated 90 degrees. Two reds go in, one red comes out.

It's really surprising how little is required to buy sodium online. I keep records of everyone I've sold hazardous materials to (from their proof of ID) and always ship under hazmat guidelines and with proper MSDS and safety information included. All it takes is a good bit of precaution and...

Re: Blu-ray / 405nm UV Fluorescence & Glow Kit (updated 6/15) As far as I know, it does not degrade over time.

Re: Blu-ray / 405nm UV Fluorescence & Glow Kit (updated 6/15) I've updated the OP to include the new UV dye, and some pictures! I've raised the kit price by $1 to account for the new addition however I'm including a free sample in all orders that haven't already shipped out since it wasn't...

Re: Blu-ray / 405nm UV Fluorescence & Glow Kit :undecided: I thought I had filled that out on my profile, should be updated now thanks for point that out. I did mention the cost of shipping within the US though so hopefully it wasn't too confusing.

Re: Blu-ray / 405nm UV Fluorescence & Glow Kit I believe I can ship to the UK for $8 instead of $4 if the USPS calculator is accurate. You can message me you're interested. Also I'm happy to announce that the latest addition I'm testing out right now is an amazing liquid fluorescent dye, the...

I agree 5 minute epoxy is great, you can bond just about anything to any surface and its very rigid when cured as well.
