Hello, I checked various laser topic on the forum but can’t find official answer on what is the rating of the enclosure and green glasses OD? Thanks

Hi @gpt1plon ; I have the 1600mW laser for my SM1. Information that is essential to get eyewear for this laser follows: Type: Class 4 Blue diode laser operating on a wavelength of 445 nanometres. The power is 1600 mW and the laser beam diameter is .5 mm. The enclosure is tinted brown and I believ…

Very useful and interesting thanks. Can these be worn over normal glasses though?

Hello John; Absolutely yes. I also wear normal glasses and this type of protective eyewear is deep enough to wear over my normal spectacles without difficulty.

Jepho, good info but i think to OP wanted to know about the glasses included with the Snapmaker 2.0. gpt1plon, I know from other posts that the enclosure has not be tested for OD (they plan on doing this later) i have not seen anything about OD testing on the glasses, my guess would be that they …

@Atom : Hi Adam; I understood the question but approached it from a different perspective. @gpt1plon was looking for official information. It can be hard to find what you need when you are starting out with a machine (and a forum support system) that is new to you. I gave the OP just as much informat…

Hello, See below answer from support: " According to our supplier, Laser transmittance is 6.5%. The OD is 1.19. But the problem is that the testing device detects the 550nm(wavelength) light while our module’s laser beam in about 450nm. We are asking the supplier to re-do the experiment. I nee…

@jepho i’m sorry, i meant no offense, and the information you provided was very good. i meant only to ask if you had any information on the glasses supplied with the unit as you did not mention them in your post and you seem quite knowledgeable in the area. please forgive my rudeness. :slight_smile: …

Hello again @gpt1plon ; Regardless of wavelength, the test page (to which I linked above) still advises 3.20 as the minimum optical density required for safety for a Class 4 laser beam of 1600mW. I would be concerned… knowing that the testing device is not testing the appropriate wavelength. It is an…

Thanks Adam; I took no offence and just supplied the facts. I am a scientist by inclination and don’t usually observe much in the way of social niceties in written communications, especially after a lifetime of writing hundreds of thousands of words for research papers. I am not particularly knowle…

@jepho i agree with you 100% 1.19 is not strong enough. i believe that what support was trying to say is that because the laser is pointed away from the user (downward) you should never receive a full 1.6W to your eyes (because to do so you would have to have the laser pointed directly at your eyes)…
