A rotary laser level set up and used to level sand fill in trenches. The graduated staff is leaning on the pile of sand. In surveying and construction, the laser level is a control tool consisting of a rotating laser beam projector that can be affixed to a tripod.
A laser line level is a tool combining a spirit level and/or plumb bob with a laser to display an accurately horizontal or vertical illuminated line on a surface the laser line level is laid against. Laser line levels are used wherever accurate verticals and horizontals are required, typically in the construction and cabinetry industries. Some ...
Laser levels are basically a more modern and precise version of the old-fashioned spirit level. Patiently eying a bubble in a glass tube never felt especially accurate – and often called for ...
Laser levels [7] project a beam which is visible and/or detectable by a sensor on the leveling rod. This style is widely used in construction work but not for more precise control work. This style is widely used in construction work but not for more precise control work.
The Y level or wye level is the oldest and bulkiest of the older style optical instruments. A low-powered telescope is placed in a pair of clamp mounts, and the instrument then leveled using a spirit level, which is mounted parallel to the main telescope. The term dumpy level (also builder's level) endures despite the evolution in design. They ...
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
