Lasers enable precision machine vision
A
Laser Components (UK) product story

Unlike lasers that use a cylindrical lens to generate a line, the power distribution of the FP-HOM series is homogenous, producing uniform power density across the whole length of the line.
FP-HOM homogenous series line lasers are now available with a broadband light source, using 680nm superluminescent diodes (SLDs) with reduced speckle pattern.
This permits more precise measurements to be achieved in machine vision applications.
The 680nm SLD produces an optical output power of approximately 3mW after optics.
All FP-HOM series Flexpoint line lasers' performance have been revised, including: maintaining constant line alignment whilst focussing; extending the overall focusing range which is now from 50mm to infinity; improving the fan angle ranges to 10, 30, 45, 60 and 90 degrees; increased output power up to 70mW, depending on the wavelength, due to a new design, thereby enabling shorter exposure and quicker processing times in image analysis applications.
Unlike lasers that use a cylindrical lens to generate a line, the power distribution of the FP-HOM series is homogenous, producing uniform power density across the whole length of the line.
Standard Flexpoint line lasers are available in 532nm, 635nm through to 660nm.
Laser diodes of other wavelengths are also available.
Other options include digital or analogue modulation and power adjustment using a potentiometer or a third wire.
