Laser calibration apparatus and method

A laser calibration device comprising:

• a housing;
• a pendulum pivotally coupled to said housing and suspending downwards therefrom;
• a laser deck mounted to said pendulum, said laser deck including a plurality of laser mounting structures;
• and
• a plurality of lasers each mounted to a respective one of said plurality of laser mounting structures, each of said plurality of lasers being pivotally and rotatably mounted to said laser deck.

A method of calibrating a laser including a plurality of laser lights mounted to a laser deck that is mounted to a pendulum, each laser light including a pitch adjustment mechanism, a roll adjustment mechanism and a crowning adjustment mechanism, the method comprising:

• adjusting said crowning adjustment mechanism of a first one of said plurality of laser lights to eliminate any crowning in said first laser light;
• adjusting said roll adjusting mechanism of said first one of said plurality of laser lights to adjust the laser line to a horizontal line;
• adjusting said crowning adjustment mechanism and said roll adjustment mechanism of remaining ones of said plurality of laser lights so that laser lines emitted from all of said plurality of laser lights are straight and horizontal;
• adjusting said pitch adjustment mechanisms for each of said laser lights such that each of said laser lines emitted from said plurality of laser lights are all on a common plane.

A laser calibration device comprising:

• a housing;
• a pendulum pivotally coupled to said housing and suspending downwards therefrom;
• a laser deck mounted to said pendulum;
• and
• at least one laser for emitting a laser line, said laser pivotally mounted to said laser deck and having a laser barrel rotatable within a barrel holder and a laser lens pivotally coupled to said laser barrel.
