What would a good OD rating be for a 1W 445nm?

Thank you for all the replies guys, you're really helpful. One other thing, what does an OD rating mean?

Very helpful, thank you!! :angel:

Hey guys, I would like to purchase a 1W 445nm soon, so i want to get a feel for how much goggles will cost. safety is my number one concern, so i want to get something good. I saw some Laserglow ones but what they say makes it somewhat complicated for me to choose the right one. Heres the link...

yea i bet its clipped. By the way, what are some advantages to a rectangular beam, if any? It just doesnt seem right..

Ah its okay, i thought you had set an exposure time, like 3 seconds or something. Its all good

You've got a nice host, small too

hey all, the names Sergiu! I've been creeping around the forums so i thought hey, why not join. I have a great interest in astronomy, and lasers, though at this point i know more about astronomy than lasers! great forum you've got going by the way. :wave:

awesome shots man! what was the exposure time on these?

Nice beam pics! gotta love 445's..

Re: 445nm 1W laser for sale Sounds great. Are the holes on the focuser evenly spaced? i read some articles saying that flamingpyro made some that weren't.

Hello, Flamingpyro! I heard your a great builder here.. I'd be interested in the services you have to offer, as i am interested in a 445 nm laser, 1W. PM me with a bit of info. Thank you!

and Tech_Junkie, i love your pic.. best stooge there ever was

Thanks for the reply. I was leaning towards a DIY one from the forums. About building one myself, im not sure yet lol. Ill definitely have to do some reading

After reading many complaints and compliments on the Arctic, i'm confused now. I really want to buy a laser, and i want a 445 nm.. but what are some reason NOT to get the Arctic? I was looking to maybe buy a DIY laser or a ray foss laser. Still unsure though. Thanks, and hopefully i put this in...

Re: 445nm 1W laser for sale Hey Tabish, nice laser you got there! im seriously considering buying this. i was going to get the WL arctic, but read that its a POS. Can you focus it? Thanks. And BTW, whats the duty cycle and beam divergence? Im sorta new to lasers..
