Installing the dichroic mirror for the He-Ne laser
Figure 5.2-10
As shown in Figure 5.2-10, install the dichroic mirror for
each He-Ne laser. (Do not attach the dichroic mirror for the
argon laser.)
• For the three-laser unit, the dichroic mirror for the
He-Ne laser located farthest from that for the argon
laser has a total reflection surface, while the middle
dichroic mirror has a green reflection surface.
• For the two-laser unit, the dichroic mirror for the He-Ne
laser located farthest from that for the argon laser has a
total reflection surface.
