…+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…

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 spread the light into an evenly illuminated
line. The result is an exceptional, uniform line with sharp ends.

…(from poorly matched
or fabricated systems). Each of these effects
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…

…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…

…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…

…structured light laser is a high-power line generator developed for the most demanding industrial applications. It is available with a wide selection of output powers and fan angles and generates a uniform intensity distribution using patented line generating optics. In addition, the laser has high…

…the flat high reflector. The long-radius output coupler acts as a weak lens to transfer the output-beam parameters. The values listed for beam divergence, beam waist diameter and beam waist location take into account the weak lens effect. The value for beam waist location is measured from the output…

…also well suited for Raman experiments in the visible region of the spectrum. Innova 70C Spectrum is a mixed gas lasers that can generate a number of laser lines from the UV to the near IR. Ultraviolet (UV) resonance Raman spectroscopy is a useful tool for the investigation of molecular structure,…
