Rotary Discs

Supplying optical encoder OEMs since 1960, Metrigraphics is a leading worldwide suplier of high precision custom encoder disks.

Through the application of our core technologies of photolithography and thin film coating with our proprietary processes, we are able to achieve the highest degree of edge definition, with line width tolerances of 1-2 microns and positional accuracies of a few arc seconds.

We offer D.C. electrical testing to confirm light transmission variation and harmonic testing to verify disk accuracy.

In addition to the custom manufacture of rotary disks to your specifications, we also offer a wide variety of standard models and lines for prototyping and production.

We’re the go-to providers for leaders in such markets as:

• Computer Peripherals
