Once the top fitting has been adjusted so the laser beam is reflecting off the center of the lower mirror it can be tightened and left alone but leave the lower fitting just finger tight so you can twist it to move the laser pattern up and down the wall or even onto the ceiling without physically tilting the box.

Optical mirrors with a metallic coating have high reflectivity over the widest spectral region whereas mirrors with a broadband dielectric coating have a narrower spectral range of operation.
Trapping light in a plastic st.
Physicists are curious to know what would be if light trapped into a mirror sphere that is a so called light trapping box.
