Glass scale technology is the industry standard and is preferred worldwide for position feedback. For nearly four decades, ACU-RITE's precision glass scale technology has proven its superior reliability through consistent accuracy and durability.

Glass is an inherently stable material that resists changes in size, shape or density due to variations in temperature or humidity. This stability allows for the generation of numerous ultra-fine line patterns; providing ACU-RITE precision glass professional scales with exceptional accuracy down to ±1.5µm (.00006").

ACU-RITE scales are available in travel lengths from 1"-773" and in resolutions from 0.5µm (.00002") to 10µm (.0005").
