Why is regular checking and calibration of rotating lasers important?
Construction sites are harsh environments that put incredible strain on rotating lasers. These instruments are not treated with a lot of care – they get dropped, knocked down or toppled over and may also become covered in dirt and concrete. In the majority of construction projects, rotating lasers face so many impacts during regular use that their accuracy can no longer be guaranteed. Like in other precision instruments, mechanical and optical parts are vulnerable to shocks and, in the worst case, might become loose upon impacts such as hard drops or heavy vibrations. This can cause inaccuracy due to the instability of the laser beam and thus, application mistakes may occur.
