Description

The Edge Sensor has specifically been developed for the measurement of mirror segments for large telescopes. In order to enable a highly precise positioning of the individual segments, the Edge Sensor detects quantities such as piston, gap and shear in nanometre resolution. The active temperature compensation reduces temperature-driven disturbances to a minimum.


Feature

  • Measurement of gap, displacement and tilt
  • Highest resolution and accuracy
  • Active temperature compensation
