2. Product Specifications and Description
2.7.2. Laser Scanning Optical path
The laser beam is reflected from the mirror [A] and passes through F-theta lens[B]. And then its direction is changed
by the reflection mirror [C]. It is transferred to OPC[D].
The polygon motor speed is controlled by the main CPU.
The LD unit generating the laser beam has the dual beam laser diode with 780nm wavelength. It is controlled by the
LD drive IC.
