Re: So are the glasses shipping with the Wicked Arctic effective?

What does a Kenometer have to do with what I posted...:thinking:
Your underwear is showing....

Post reported....:cool:

Re: So are the glasses shipping with the Wicked Arctic effective?

I thought a kenometer was used to measure laser amplitude?
 
Re: So are the glasses shipping with the Wicked Arctic effective?

Nice try.... no sale... I know who you are....:cool:

whatever, just delete this.

i will ask a simply phrased complicated question another time
 
Re: So are the glasses shipping with the Wicked Arctic effective?

Despite the sidetrack, it is a very valid question as to these glasses. Everyone inexperienced will receive these glasses and assume they are safe for use with this laser, but I have yet to see a single OD or wavelength rating, or a single statement of certification for effectiveness. No ANSI standards, no OD, nothing. Just "safety glasses".
 
Re: So are the glasses shipping with the Wicked Arctic effective?

and the stickies referencing *real glasses* don't do much more than reference brands. These need to provide real data.

Back in the day pseudo tested these IIRC, I thought he may have made a thread about it. Anybody know where this thread is?

The reputable brands are the ones who *supply* the data. The maker/tester of the glasses are the ones who can actually certify these things. Hobbyists aren't equipped to truly test goggles to the certifications like ANSI, and even for the hobbyists who are equipped, it's not worth all the time and effort in reinventing the wheel when we can just buy certified goggles in the first place.

Such as with OEM, which states clearly on every page "All our protective eyewear meets ANSI Z136 standards and most meet EN207 standards." Then each filter type lists something like this, given for the ARG lens:

ANSI Z136 Specifications VLT Lens Color
OD 7+ @ 190-532nm 48% Orange

EN207/208 Specifications Mode Rating
180-315nm D L7
180-315nm IR L4
>315-532nm DM L5
>315-532nm IR L6
 
Re: Goggles for 445nm

I dont think the cheep FP glasses will be good for more than 300mW!
Hear is the dot at about 15ft, and 3ft from camera to dot. 361mW 445nm

A direct hit or spectacular reflection at this power will be bad IMHO.
These new diode's are serious power, and not to be underestimated! I am not going to make this any higher power tell I get proper glasses.
These realy only protect from the ambient light from the dot at a distance.

Re: Goggles for 445nm

what's exactly shown on that photo? the dot on a wall seen from behind the goggles? Can you try to aim the laser at the goggles for 1 min and tell us what happens?
 
Re: Goggles for 445nm

Yeah, well, but believe it or not, those hold 200mW of 405nm and 200mW of 532nm for one minute without melting. And yes, they are 7$ LoL
