1. Loosen the slot-tightening screw and three
sleeve-retaining screws to allow insertion of the laser
head.
2. Insert the He-Ne laser head into the sleeve. To
prevent leakage of scattered laser light, press the
end of the laser head against the black ring attached
to the plate just enough to compress the ring slightly.
Make sure that the label on the He-Ne laser is facing
upward when installed.
3. 405 (for cylindrical type)
• Use the focus adjustment tool provided with the
laser to adjust the laser to give a minimum beam
diameter at 1.5 m to 1.7 m distance from the
emitter.
(This must be performed to increase transmission
efficiency across the fiber connection and to
ensure that the light controller is operational.)
• Insert the 405 laser head into the sleeve, making
sure that the emitter end adapter is pressed
against the plate. Confirm that the label on the
405 laser faces to the outer side when installed
(elliptic shaped beam is in vertically oriented).
