Laser equipment
Axis, Optical Axis
Industrial machinery; Laser equipment
The optical centerline for a lens system; the line passing through the centers of curvature of the optical surfaces of a lens.
Beam
Industrial machinery; Laser equipment
A collection of rays that may be parallel, convergent, or divergent.
Beam Bender
Industrial machinery; Laser equipment
A hardware assembly containing an optical device, such as a mirror, capable of changing the direction of a laser beam; used to repoint the beam, and in "folded," compact laser systems.
Beam Diameter
Industrial machinery; Laser equipment
The distance between diametrically opposed points in the cross section of a circular beam where the intensity is reduced by a factor of 1/e (0.368) of the peak level (for safety standards). The value ...
Beam Divergence
Industrial machinery; Laser equipment
Angle of beam spread measured in radians or milliradians (1 milliradian = 3.4 minutes-of-arc or approximately 1 mil). For small angles where the cord is approximately equal to the arc, the beam ...
Beam Expander
Industrial machinery; Laser equipment
An optical device that increases beam diameter while decreasing beam divergence (spread). In its simplest form consists of two lenses, the first to diverge the beam and the second to re-collimate it. ...
Beam Splitter
Industrial machinery; Laser equipment
An optical device using controlled reflection to produce two beams from a single incident beam.
