Cleaning
When the PEM was shipped, the surface was clean and defect free; however, the
rigors of packing and shipping may leave some residue on the optical surface(s). A
final cleaning of the optical surfaces may be required before using them in your
system.
As with all optics, dirt, fingerprints, oils and other materials lower the effectiveness
and shorten the lifetime of dielectric coatings.
Handle all optics with care to prevent unusual wear, breakage or surface scratches.
Recommended Optics Cleaning Solutions
It is important to use the proper cleaning solution for specific optic materials.
Failure to use the proper cleaning solution may scratch or damage the optical
surface.
Coated/Uncoated Non-ZnSe Optics
The non-ZnSe optics are coated with a hard, durable dielectric material and may be
cleaned like an uncoated optical surface. The optic may be cleaned with
uncontaminated acetone .
Coated/Uncoated ZnSe Optics
The ZnSe optics may be cleaned with lighter fluid/butane.
Avoid exposing the junction between the optical element and the transducer with the
solvent.
