Trying to find the right protective eyewear...
« on: December 27, 2018, 12:00:55 PM »
Hey all...

I have an AlphaAutomation 3000mW diy blue laser engraver kit. https://alphautomation.com/collections/laser-engraving-machine/products/3000mw-blue-cnc-laser-engraving-machine

I want to get a better set of eye protection, but I am not sure as to which to get.

I know that the laser is a blue 3000mW 450nm laser, but I am not sure about the OD aspect.

If someone could offer some advice as to what I should be looking for, that would be appreciated.

Thank you for looking!
JP

After my eyes got scratchy because of the included glasses, I did some research and found these:

I bought two pairs and am VERY pleased
Laser: A5 2000mw with L7 Board / A3 2500mw PWM with Mana SE -- All using T2Laser
3D Printer: Monoprice Maker Select v2.1

There are red protective glasses available for a few dollars that work very well, the supplied glasses are downright dangerous, not even the correct colour and are around an OD5 at laser wavelength, the red ones are at least OD12 (10 million times safer) and compare well to an arc welding mask at OD14.
I still NEVER look at the laser at all at cutting or engraving powers unless using arc welder glass and even that would be insufficient for a highly reflective surface. They are not intended for the powers a high power beam can put out, not much is.
Also remove all pets from the room etc. Last time I had an optician check up I had him check my retinas and no new damage, lots of old stuff from my work with the defence industry decades ago.

There is full info on the correct glasses to use on this forum...Try SEARCH.

Lasers are wonderful machines..not ONLY  can they cut a finger off BUT  they can also cauterise it at the same time.....

SAFETY -  IS NO ACCIDENT
