Glass scale gratings are available in a variety of configurations. They are intended for applications where the user provides the scanning unit and the electronics to create a customized measuring or detection system. The quality glass gratings are available as linear scales up to ***0 mm length, as disco shaped scales with diameters up to **0 mm, or in special geometric configurations.
