I'm concerned. A one watt laser pointer for less then 200$ is a problem in the hands of those who are immature. If your running a group buy, the repercussions of this are on your heads.
I don't give a damn about lack of enforcement of federal laws in the US or Free Will or Personal Freedom. Let me rephrase that, I do give a damn about my ability to purchase tools, parts, and materials to do my job as a laser professional and my freedom.
In other words, please think twice before you sell blue kits at 200$ or less to some one who lacks maturity. Your shortchanging your own rights in the long run.
The federal government is failing on enforcement to the point that laser safety will pass to the state level, and that would be a non uniform mess. Five years ago this device would have had safeguards to prevent diode removal. It needs to be retrofitted right now to diodes bonded to a sled. That would make it a better projector for its intended use, anyway.
I hate to be a Cassandra (Greek Mythology, look her up) , but I ask
Those of you organizing massive group buys need to think about what your doing and whom your selling to.
At 700mW to 1 watt, injuries will be all too common, and blue has some unique short and long term PROVEN side effects with respect to color vision. Prolonged exposure to intense blue results in diminished green vision. This has been proven in studies of eye surgeons who used blue lasers to treat patients. The green vision comes back somewhat in 3-6 months. The surgeons were exposed to milliwatts at best for 20-40 minute sessions per patient.
Argon multiline blue/green has been largely replaced by green and yellow-green wavelengths for retinal surgery, blue/green was used because it was what was available with the technology of the time. Surgeons have long decried the tissue side effects of blue green, and only in the past 5 years has DPSS made its way into eye surgery.
This blue wavelength has some unique biochemical actions on releasing free radicals, and is strongly adsorbed by red blood cells in capillaries. It causes larger damaged areas in retinal tissue and is far more likely to be adsorbed by the tissue then 532 nm light.
I'm not open to arguments on this one, I've worked with 488 nm light since 1989 or so.
There is no legitimate non military need for a watt of collimated visible light in a hand held device.
You certainly have the right to blow out your own retinas. But when you affect others the game changes.
Blue glare in a aircraft will NOT be a good thing.
Don't even bother to make the lame comments about the poorer beam quality, high divergence, etc.
167 people are looking at this thread as I type. Wait till it gets slashdotted, kipcayed, etc..
It is to the communities advantage to self regulate, restrict buyer age, make buyers sign a warning notice, and to drive the price upwards.
Your new laser regulator will NOT be the CDRH if this gets out of hand. It will be the FAA, US Customs, Homeland Security, and your LOCAL POLICE. FAA had no problems getting a instant moratorium on outdoor laser shows some years ago, and the FAA can and will get enforcement instantly, if this gets out of hand. And it will be a FELONY and CIVIL PENALITES.
Freedom is not free, it comes with great responsibility.
You have been warned. You can also bet I and others will be calling Casio first thing Monday Morning.
