A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers— ultraviolet , visible , infrared , continuous wave , pulsed, high-power, low-power—there is an assortment of instrumentation for measuring ...
Tophat beams are often used in industry, for example for laser drilling of holes in printed circuit boards. They are also used in very high power laser systems, which use chains of optical amplifiers to produce an intense beam. Tophat beams are named for their resemblance to the shape of a top hat.
BlueLine Rental, formerly Volvo Rents, was an American company that rented construction equipment to contractors and retail consumers through a network of company owned stores. The company specialized in renting a variety of construction equipment, ranging from small tools and light towers to large earthmoving equipment.
By observing and recording the beam pattern, for example, one can infer the spatial mode properties of the beam and whether or not the beam is being clipped by an obstruction; By focusing the laser beam with a lens and measuring the minimum spot size, the number of times diffraction limit or focusing quality can be computed.
Equipment rental was first developed in Anglo-Saxon countries. It emerged in the UK after the First World War and has now become a multi-billion euro business providing a wide range of construction and industrial equipment for customers globally.The American Rental Association was founded as early as 1955, [1] and the first waves of consolidation took place in the 1970s in North America ...
In Canada, steel I-beams are now commonly specified using the depth and weight of the beam in metric terms. For example, a "W250x33" beam is approximately 250 millimetres (9.8 in) in depth (height of the I-beam from the outer face of one flange to the outer face of the other flange) and weighs approximately 33 kg/m (22 lb/ft; 67 lb/yd).

In structural engineering and construction, a gusset plate is a plate for connecting beams and girders to columns. A gusset plate can be fastened to a permanent member either by bolts, rivets or welding or a combination of the three. [1] They are used in bridges and buildings, as well as other structures. [1]
Cross-sections of continuously rolled structural shapes, showing the change induced by each rolling mill. Structural shape rolling, also known as shape rolling and profile rolling, [1] is the rolling and roll forming of structural shapes by passing them through a rolling mill to bend or deform the workpiece to a desired shape while maintaining a constant cross-section.
