Making an Incident Beam Adjustment of the Optical Fiber
Since this laser adopts a high-precision optical fiber, no adjustment is required when
the fiber is mounted or dismounted once an incident beam adjustment is finished.
For the optical fiber models SIH-□□, no readjustment is required at replacement.
However, after a laser oscillation adjustment and optical axis adjustment, after
removal of the beamsplitter, input unit, beam expander, YAG rod or laser chamber,
after replacement of the Ø 0.2 mm optical fiber, and after shift of the YAG laser optical
axis, incident adjustment is required.
⇒
For the incident beam adjusting method, contact us for information.
<Note>
Use an optical fiber specially intended for incident beam adjustment. If any other
type of optical fiber is used, the optical axis of incident beam may be dislocated in
installing, detaching or replacing the fiber, which will result in damage to the end
of the fiber.
Cleaning the Optical Fiber
When the optical fiber is dirty, perform cleaning.
WARNING
■ Be sure to receive education for this work from our engineer.
■ Before starting work, be sure to turn OFF the power supply.
Item required
Air blow, lens cleaning paper, and end face checker
Operating Procedure
(1) Remove the optical fiber from the input unit or output unit.
(2) Blow off foreign particles by using the air blow.
If the foreign particles on the end face cannot be eliminated, wipe it lightly with
the cleaning paper.
