Description

The BH25 is a high resolution exposed linear encoder with interferometric measurement signal generation. The BH25 scale has a graduation period of 1µm. The interferometric laser scale principle generates a sinusoidal measurement signal with a signal period of 250nm in the read head. The BH25 is characterized by its small size and high signal quality. It is suitable for resolutions of up to 3.8pm. Due to the reflective scanning and the small design it is perfectly suited for high accuracy X/Y stages with linear motor drive as well as for measurement applications
