Optics cleaning guide

Optical Surfaces Ltd.

Optical Surfaces Ltd. has published a new guide to provide scientists and engineers with expert advice on maintaining the performance of their aluminum coated optics.

After a time, depending on the environment in which coated optics are used, they may become contaminated with dust or stained. Dust and stains can cause scattering, and impurities on the surface of the optics can react with incident light resulting in damage to the optical coating.

Starting from the premise "If it's not dirty, don't clean it" the new guide describes a simple to follow 5-step progressive process for cleaning coated optics in a clean, low dust environment.
