7. Create acyan beam eect (point) and check visually
whether the green beam hits the exact centre ofthe
blue beam atthe dichroic filter DF4. Ifnot, use dichroic
mounts DF3 to adjust the beam path accordingly.
Toadjust the dichroic mount use the two adjustment
knobs – each works for one axis.
8. Createa full size cyan circle (static tunnel eect) and
check whether the green circle overlays the blue
circle inall points around the shape. Ifnot, use dichroic
mount DF4 to adjust the beam path accordingly.
Toadjust the dichroic mount use the two adjustment
knobs – each works for one axis.
9. Createa full size magenta circle (static tunnel eect)
and check whether the red circle overlays the blue
circle inall points around the shape. Ifnot, use dichroic
mount DF1 to adjust the beam path accordingly.
Toadjust the dichroic mount use the two adjustment
knobs – each works for one axis.
10. Finally create afull size white circle (static tunnel eect).
Ifthe alignment procedure was done successfully you
can see all the colours nicely overlaying each other,
resulting ineven, bright and sharp circle like the one
onthe picture below.
