Laser Beam
The laser beam is pulsed On and Off by the digital signal (nVIDEO) to form a latent image of two different
voltage potentials on the drum, as shown below.
Laser Diode Specification
6.3.4.3.
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.
