I don't get this.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.
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.
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.
It is to the communities advantage to self regulate, restrict buyer age, make buyers sign a warning notice, and to drive the price upwards.
You have been warned. You can also bet I and others will be calling Casio first thing Monday Morning.
First, I'd like to point out that this was written almost two years ago. The predictions did not come true. Injuries are NOT all too common. In fact, they are still surprisingly rare.
It is more like Chicken Little than Cassandra.
Second, this forum seems to live and breath on finding the next great diode or projector with a great diode in it - and yet this stickied post calls for everyone to stop buying diodes and stop buying projectors, stop doing group buys, raise the price of handheld lasers, etc...
The post even goes so far as to suggest calling the projector companies and tell them to make the diodes un-harvestable. How is that of any benefit to a forum in which the members are trying to build laser pointers from diodes that are almost always harvested from some sort of projector or optical burner?
Please don't get me wrong, I am 100% for eye safety. I am 100% for aircraft safety. But I don't see how trying to get manufacturers to quit making products in a way that we can get the diodes out of them is in any way a positive thing for the forum.
So, what am I missing here? :thinking:
