For more than 40 years, our clients have placed their trust in us for the design and production of high-precision optical encoder discs and linear scales.

We produce incremental encoder disks, absolute encoder disks and linear scales on glass and film.

We offer different types of manufacturing to meet all operating modes, including reflection operation.

The flexibility of our production methods allows us to offer you products according to your specifications, in small or large quantities with excellent responsiveness.

The rotary encoder disks and linear scales produced in our workshops are used in many fields such as robotics, motion control, etc..
