Discussed a lot of times - see here:

> [@Question about laser safety in enclosure](https://forum.snapmaker.com/t/question-about-laser-safety-in-enclosure/7502):
>
> Hi! I just received the backerkit and was looking at the enclosure. Someone mentioned that the optical density (OD) of the enclosure’s panels is OD1. Is this true? Thank you.

or here:

> [@New 10W laser requires the enclosure?](https://forum.snapmaker.com/t/new-10w-laser-requires-the-enclosure/23705):
>
> I preordered the new 10W laser and i am just wondering if this statement is just an advise or mandatory. “This is a class 4 laser product. You should always operate the 10W High Power Laser Module with the Snapmaker 2.0 Enclosure covered.” Are the provided laser goggles with the NEW laser enough protection? (without the enclosure) How about the old goggles? The old module has a wavelength of 450nm and the new one of 450-460nm.

and there’s more.
