Hi, I have read many posts and articles about laser pointers (up to 200mW). I d like to ask you few questions because I am not sure if I understad to lasers enaught yet. (sorry about my English, I am from Czech)
1. IR and power in mW
Can be said that laser beam is consisted of 2 different rays (beams) ?
1.1 From IR ray which can be reduced to 0% by IR filter which is installed inside laser pointer (the quality ones). So If there is IR filter, I dont have to afraid of this ray.
1.2 From "laser ray" at certain power in Watts (mili W) which can be reduced by special goggles (glasses) ?
Q1: Are goggles 100% safe for my eyes? (let say for lasers up to 200 mW) Can I look into laser beam with theese goggles withou risking eye retina damage (just hypotethycaly)?
Q2: Is IR beam dangerous too (I know it is, but how much)? If laser has built-in filter, my eyes will be safe?
2. Power and your eyes
I have read that 5mW is the limit. Over 5mW your eyes could be damaged.
Q3. Can anyone write here his own experiences with this? Has anyone got hit his eye? Please write in this thread:
Laser type (color or/and nm)
If you got hit by reflection or got direct hit
Time how long it lasts
This will help not just me, but all other people (newbies included).
3. Are Eye damages permanent?
Somebody wrote that got hit but after few hours/days his eyes went good (they healed). One user (Xoul) wrote he got direct hit by 1W laser and had to go to surgery. Anyone knows how is he now? Is he OK?
Q4. Can be said that green lasers up to 30mW will not damage your eyes permanently?
Q5. If you damages your eye retina permanently (can it be by reflection of 100mW green laser?), is it for all your life? Cannot be fixed by doctor?
Please dont "spam" here. If you wanna say me something like: "U are noob" or "use google" , please use PM. I have already read FAQs too
I would like if most experienced laser fans / scientists ;-) reply in this thread. Hope this thread will be usefull for everyone.
Thank You all very much.
