I read that cheap green laser pointer may emit high levels of IR that can damage eyes. I happen to have a cheap green laser pointer and have some questions:
- if I point the laser into the sky, can the high levels of IR still injure my eyes or cause other danger?
- do red or violet laser pointers leak IR or just green?
Given the same power consumption (NOT output power), what color laser pointer would be brightest? Red because the pointer is more efficient, or green because our eyes are more sensitive to the color?
What is the cheapest green laser pointer that does not leak IR and where do I buy one? I found one at laserglow for $39 that specifically say it does not leak IR. Is this a good buy?
