Comparison with Taurus - 2

In the Taurus, each color has a
separate VCSEL unit, but each
polygon mirror handles two
colors.

Beams arriving at one side of
the mirror are sent to one PCU,
and the beams arriving at the
other side of the mirror are sent
to another PCU.

In the Ch-C1, each VCSEL unit
handles two colors. Instead of
just one polygon mirror for two
colors, there is a stack of two
mirrors (one mirror for each
color).

The prism just after the exit
from the VCSEL unit sends
some beams to the top mirror
and some to the bottom one.
