BL50H High resolution linear encoder

The BS78 is a high accuracy exposed linera encoder with an interferometric signal generation in transmitted light design. The scale has a graduation period of 0.55µm. The LASERSCALE operating principle generates a sinusoidal measuring signal with a signal period of 138nm. This has an extremely high signal quality with a very low noise component. This allows resolutions of up to 2.1 pm to be generated. Due to the extremely low interpolation error, the BS78 is perfectly suited for ultra precision machining, measurement and calibration applications.

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

The BL57 is a high-resolution, exposed linear encoder with interferometric operating principle in transmitted light design. The BL57 has a graduation period of 1.6µm and generates a sinusoidal signal period of 400nm due to the laserscale operating principle. This allows resolutions of up to 6.1pm. to be achieved. Due to the high response speed of up to 3m/s, it is perfectly suited for high-precision and fast X/Y stages.
