It lacks your details but for better or worse that’s the way.

Will the mirrors used for the laser need to be cleaned/replaced very often?

Thanks for the kind words @elsman18 and all. Quite correct, the mirrors are completely enclosed behind laser-transparent windows that are easy to wipe and should last forever. If something does happen to the windows, they can be easily user-replaced, but that should never be necessary if you’re careful with them.
