Powell Lens

2. Powell Lenses are optimized for a 0.8mm diameter laser
beam otherwise called Laser Line Generator Lenses,
convert laser bars into uniform, straight lines. In contrast to
round and hollow focal points, which create Gaussian beam
focal points with hot spot center and fading edges, Powell
Lenses give a uniform distribution of energy along the
length of the whole line.
The Powell Lens looks like a round prism with a bent roof
line. The focal point is a laser line generator, stretching a
narrow laser beam into a uniformly lit straight line. The
Powell lens quantum jump forward in line generator
performance over the simple cylinder lens.
Then a cylinder lens delivers an inadequately lit up beam,
one constrained by the non-uniform, Gaussian laser beam.
The Powell lens round roof is actually a compound two-
dimensional aspheric bend that creates a lot of sphere-
shaped deviation that redistributes the light along the line;
diminishing the light in the center point while expanding
the light level where the line finishes.
The outcome is a uniform lit up line utilized in all method of
machine vision applications; from bio-medicinal and
automobile assembly to chocolate chip cookie creation.

3. The width of the Powell Lens fan angle is a work
actually done by a refractive index of the glass
and the roof angle. The refractive index increases
with the increase in roof, also the line of the
given projection distance increases with the
increased width of the fan angle.
Small fan angles usually use optical glass of a
moderate, n=1.5, refractive index. Large fan
angles are usually made with a high index glass,
n= 1.8, or higher to minimize the roof's otherwise
steep angle.
Fan Angle

4. The manifested laser beams dimension and measurement
decides the thickness of the laser line at a given projected
distance. A collimated laser diode includes a circular beam
cross segment permitting either a thin or thick line capability
with only one diode module.
With a thin incident beam orientation, the beam’s main axis is
parallel to the Powell lens roof and a slim laser line with a
little depth of focus is produced. With a wide incident beam
orientation, the beam's main axis is perpendicular or upright
to the Powell lens roof and a thick laser line with a large
depth of focus is produced.
Laser Beam Size

5. Powell focal lens execution is effected by the laser
beam’s characteristics and features, it is also
effected by the nature and quality of the lens
aspheric surface. For requesting applications, a
consistently lit up laser line is best obtained by
matching the Powell lens to the laser module's
particular beam characteristics.
Powell lens consistency isn't a flat out trademark,
it is subjected to the testing strategy and
techniques. For instance, the uniformity measure
will rely upon whether one is evaluating the
Powell lens’s anticipated line as observed on a
surface by a camera in a machine vision
application or sweeping a detector across the
diverging fan of light for laser safety assessment.
The distinctions in consistency attributes to the
increase in fan angle, beyond 20 degree Powell
Lens divergence, the dissimilarity and divergence
become a noteworthy phenomenon, and this
changes can easily be assessed and understood.
Line Uniformity

6. The main 80% of an evenly lit up line will
contain 80% of the energy. A lower
contained energy will cause the ends of
lines to increase in brightness and these
ends will be more illuminated. Limiting the
peaks results in better use of the laser's
available power.
