Description

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.
