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.

Optical Surfaces Ltd has been producing optical components, mounted optical components and systems for more than 50 years and is now accepted as one of the world’s leading manufacturers of high-precision optics and optical systems. The company’s ISO 9001-2008 approved manufacturing workshops and test facilities are deep underground in a series of tunnels excavated in solid chalk where temperature remains constant and vibration is practically non-existent. With such stable conditions testing, particularly with long path lengths, becomes quantifiable and reliable. Working with these natural advantages is a highly skilled team of craftsmen with a commitment to excellence in both product quality and customer service.
