…on the line length. Such a high
aspect ratio of the line beam field is generated by independently shaping the two axes of the homogenized excimer
laser beam. The long-axis dimension is defined solely in
the homogenizer, which therefore includes a cylindrical
condenser lens in the…

…+3...) and the negative orders
on the other side (-1, -2, -3...).The spreading angle, s,
between the two outmost beams (or lines, when a
line generating lens is added) is twice the angle of the
higher order beam.
For example, for a 5-line pattern at 670 nm with a
period…

…is produced by a standard refractive line generation lens followed by
a diffractive optic to produce multiple lines (i.e., multiple orders). The critical
parameters here are the grid shape and size, i.e., line linearity, parallelism,
line spacing, and high pointing accuracy…

…laser line patterns are often generated by cylindrical optics that produce a Gaussian line profile with a
bright center and fading ends. Coherent patented beam shaping optics distribute the light into an evenly illuminated
line. The result is an exceptional, uniform line with sharp…

can lead to measurement errors.
Most laser line generator manufacturers
specify line uniformity as the variation in
the intensity profile from the average intensity value over a given region. Usually, this…
