Laser Level

<< >>
Description
Lasers have proven very useful in the construction industry. One example is this Spectra-Physics model 910 "LaserLevel" made in the early 1980s. In use, a construction worker attached the unit to a tripod and adjusted it so that it was nearly parallel to the ground. The level automatically completed the adjustment process when activated, and then emitted a beam of infrared light from a rotating head. The worker then moved to where-ever a measurement was needed and used a special laser detector to complete the task.
The "LaserLevel" self-adjusted if bumped slightly and completely shut off if bumped too much. The level operated automatically so it allowed one person to do work of two, resulting in cost savings since fewer assistants were needed.
