Lasiris™ Line Advantage
The Non-Gaussian Distribution
Most laser line generators on the market today use cylindrical optics to generate a line. We use a special Lasiris lens system that makes the lines non-gaussian (uniform) in intensity, even when the laser is off-axis. The Gaussian or Non-Gaussian distribution refers to the distribution of power over the projected laser line. The phrase Gaussian Distribution (also called Normal Distribution) is a statistical term that refers to a bell-shaped graph.
Non-Gaussian Lines are Efficient
The
light intensity of a Gaussian line fades away towards the ends of
the line, eventually falling below the threshold level of the detector
and becoming invisible to the system. Depending on the settings
of the detector and the level of uniformity required by the application,
as much as 50% of the available power can be lost.
Non-Gaussian Lines are Easy to Calibrate
Because
the light intensity of gaussian lines is non-uniform, the calibration
of CCDs can become very difficult. Separate calibrations must be
made for pixels in the bright central area and for those in the
transition area. The low intensity area cannot contribute to the
calibration because it is invisible to the system.
Non-Gaussian Lines can Eliminate Safety class Problems
The hot spot (central part) of a gaussian line is often a great deal brighter than the rest of the line, pushing the laser into the next level of safety ratings.
