Cleaning The Optics

Unlike general mechanically processed parts, the surfaces of optical components are unusable
when they are scratched or burned. Please use extreme care when handling any optical
components. To clean optical components, use the air blower, ring wrench, acetone and lens
cleaning paper. CAUTION: Do not use any other materials for optical component cleaning.
Note: Please contact the factory if you wish to do maintenance
work on the optical components other than the input focusing unit
and the optical fiber.
Optical Component Cleaning Tools and Materials. The required optical
component cleaning tools and materials are illustrated in Figure 8-10.
Figure 8-10. Optical Component Servicing Tools
Removing the Input Focusing Unit Optics. Refer to Figure 8-11. To remove the
input focusing unit optics for cleaning:
1. Remove the input focusing unit from the laser.
2. Remove the threaded ring by turning it.
3. Hold down two sheets of lens paper on the lens holder end of the input focusing
unit.
