Polygonal Mirrors


Diamond Machined Mirrors

Diamond machined polygonal mirrors are manufactured from 5052 and 6061 aluminum alloys as well as copper.

Surface figure: lambda/8 per inch typical

Surface roughness: 40-80 Angstroms rms depending on configuration

Optical coatings: Wide variety of gold and enhanced aluminum coatings available

Polished Mirrors

We offer conventionally polished polygonal mirrors for applications where low scatter is critical such as film or UV scanning applications. These mirrors are constructed of 6061 aluminum with a electro-less nickel overcoat.

Surface figure: lambda/8 per inch typical

Surface roughness: <= 10 Angstroms rms

Optical Coatings: Wide variety of enhanced aluminum coatings including the deep UV.
