Cleaning And Inspection; Protective Windows - Aerotech AGV3D Series Hardware Manual

4.2. Cleaning and Inspection

4.2. Cleaning and Inspection
There are no elements on AGV3D stages that require lubrication.
Before using a cleaning solvent on any part of the AGV3D, blow away small particles and dust with nitrogen
or, less preferably, clean, dry, compressed air.
Any external metal surface of the AGV3D can be cleaned with isopropyl alcohol on a lint-free cloth.

4.2.1. Protective Windows

Optical surfaces that are contaminated with dirt and debris result in increased absorption of laser radiation.
Over time, this contamination can cause the optical surfaces to absorb enough heat to cause permanent
burn damage. There are several different kinds of optical surface contamination:
Airborne particles in the ambient atmosphere – dust, grease, etc.
l
Products from the laser process – vapors, back spatter, burned-in particles, etc.
l
Organic contamination – particles produced by talking, coughing, or sneezing near the optical surfaces.
l
Wherever possible, protect the exposed optics to avoid contamination. However, since contamination
cannot be completely avoided, you will have to periodically clean the optical system. Regularly inspect and
clean the optical surfaces to help prevent permanent damage.
W A R N I N G : Contamination from the laser process can cause irreversible damage to the
optical surfaces. To help minimize contamination, use an exhaust or vacuum system.
Optical materials and coatings are relatively soft substances and incorrect cleaning techniques will result in
surface damage and drastically reduced component lifetime. The cleaning procedure for the AGV3D is
intended to help prolong the component lifetime.
W A R N I N G : Fingerprints contain aggressive substances that can damage optical surfaces.
Always wear suitable gloves when you handle the optics.
W A R N I N G : Before performing any inspections of the focal lens, verify that the laser is
switched off and secured against accidentally being switched on.
W A R N I N G : Take extra care when cleaning a focal lens that does not have a protective glass
window.
