LD Unit Components (VCSEL Technology)
This machine uses a new technology called VCSEL.
Each VCSEL LD unit has 40 beams in a two-dimensional array.
VCSEL allows magnification correction and fine adjustment of
image position.
VCSEL also keeps the strength of the laser beams constant by
optical waveform correction. This correction is important for
reproducing thin diagonal lines.
