Improvement of the conventional design of kinematic mirror holders (MHG) . These holders are suitable for experiments which use a large number of simple mirror holders or for incorporation of mirror holder into production devices.

  • These thinned holders can offer larger space for adjustment work compared to MHG.
  • These holders hold a mirror at three points from the side in order to adjust the stress occurring when holding the mirror.
  • Retaining rings do not cause constraints on the clear aperture so that a large clear aperture can be obtained with reflected light or transmitted light.
