Laser equipment
Axicon Lens
Industrial machinery; Laser equipment
A conical lens which, when followed by a conventional lens, can focus laser light to a ring shape.
Axis, Optical Axis
Industrial machinery; Laser equipment
The optical centerline for a lens system; the line passing through the centres 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 ...
