thx udanis for the quick reply,

if I got it right an OD of 2.5 wont be enough with this baby,
at least 3.5 or 4 is needed to be on the safe side, correct?

They will still handle some 445nm.

Ideally they should be higher.

i dunno the od but they work and 1-watt 445 for ex. is greatly squeltched.
you can look at whatever you're burning with no problems and no after-images .
i dont own a light meter .
but go ahead spend your money on expensive ones, if you want .

With out a light meter you can't really recommend things like that. If you tested them then ok but it's seems you have not.

there is a whole section of the forum for safety discussion and many threads which contain info on specific goggles/glasses.I would read through some of those threads before you buy your glasses.otherwise you may not get adequate protection.

yeah, ok, I will

didn't really want to start a completely different discussion.

Anyway, nobody likes to throw away money, so thx Heirophant, I'll check them out along with some certified one.

just a quick question yob:
Is there any kind servicing you offer on these lasers?
(ex: diode extinguishes, Send laser + money(for new diode/service) to yob for repair)
If not, will you eventually be releasing a service guide on how to replace parts?

Thanks~
