Method and apparatus for construction of modular galvano motor scanning heads

An apparatus of galvano motor scan head or scanning head or scan block modular construction to achieve a modular galvano motor scanning head product whereby multiple galvano motor and multiple galvano motor driven scanning mirror substrates and/or multiple beam expansion or beam collimation or beam de-collimation or beam window input optics and/or multiple delivery optics and/or multiple galvano motor drive electronics may be used to produce said modular galvano motor scanning head dependent upon customer required configurations whereby larger diameter casings are used to clamp around a galvano motor body without contact to or hinderance of a beam steering or galvano driven scanning mirror and are fixed in position by a retaining fixing whereby;

• a) said galvano motor locates to its correct depth position in relation to the correct position for said beam steering or galvano driven scanning mirror to intersect a beam path, and
• b) said larger diameter casings locate to their correct depth position against a locating flange engineered into said scan head or scanning head or scan block in relation to the correct position for said galvano motor indexed as described in a) above and therefore said beam steering or galvano driven scanning mirror intersects a beam path at the correct depth.
