This adjustable mirror holders are used for standard mirrors, pirror prisms, dichroic mirrors, beam splitters etc.
The 45° bevel allows to use standard mirrors or dichroic mirrors without rotating the mirror holder by 45°.
One of the advantages of this mirror mount is the form-stability. Compared to 3-aixis mounts our mirror mount is not based on the train-pressure principle. Due to the tension 3-aixis mounts may get displaced by thermal or mechanical (vibration) influence.
