1.9.3. Collimator Lens
The collimator lens converts light from the laser diode to parallel light. This aids in scanning and provides better convergence to a
dot.
1.9.4. Polygon Scanner
The polygon scanner consists of a 6-sided mirror directly driven by a brushless DC motor at a rate 20,078.74 rpm. The laser beam
is reflected across the OPC drum by the mirror faces and produces the scan. One mirror face is equal to one main scan.This unit
features stable line scanning speed, precision mirror surface reflection angle, reflect-free surfaces, and instant start.

1.9.5. Cylindrical Lens and
Lens
Each of the polygon mirror surfaces has a slight imperfection. This prevents the beam from scanning the OPC drum surface at the
constant interval in the sub-scan direction. The cylindrical lens and
lens are used for correcting this uneven laser scanning.
1.9.6.
Lens
This lens ensures that the beam scans across the surface of the OPC drum at a constant rate. The beam is refracted to parallel
light as it passes through the lens to ensure that the dots at the edge of the drum and at the center of the drum areequally spaced.
This lens also provides a set focal length for laser beam.

1.9.7. Timing Sensor
This sensor detects the laser beam and determines the start timing for scanning. A pin photodiode is used as the timing sensor.
