Use Of A Laser To Measure Flatness

Flatness is a term used when measuring the uniformity of a horizontal surface.

While a conventional shop level and straightedge are fine for measuring the flatness of small surfaces, when it comes to large horizontal areas these tools are potentially inaccurate because they must continually be moved and the flatness of the entire surface cannot be simultaneously measured.

Previously, measurement of the flatness of large surface areas required extensive time, manpower and machinery. Now, inexpensive and easy to use 'laser levels' can provide a quick, easy and most importantly, highly accurate way to determine the flatness of large surface areas.

Use of a laser level for leveling and determining flatness involves sweeping a laser beam horizontally, making a perfectly horizontal 'plane of sight' that is sometimes known as a waterline. This allows flatness to be determined to within a few thousands of an inch, over distances of hundreds of feet.
