1. 29 LASER MEASUREMENT SYSTEM System accessories OPTICS ACCESSORIES OPTICS MOUNTING KIT This kit provides the essential elements required to mount the Renishaw optics to a machine Optics can be easily interchanged without the need to re align the laser It comes with hard anodised aluminium mounting blocks stainless steel pillars and bases for the optimum combination of portability and durability They also incorporate M8 threads for attachment to standard magnetic bases or Renishaw s CMM probe heads SWIVEL MIRROR FIXED TURNING MIRROR This mirror can be used as an alignment aid for ANSI B5 54 diagonal measurements It is also useful when measuring slant bed lathes Clamping screws allow the mirror to be easily attached to measurement optics This mirror reflects the laser beam through 90 Like the swivel mirror it can attach to the measurement optics to aid optical set up and is used primarily when there is restricted access to the required axis of measurement BEAM STEERER L 8350 This unique optic provides easy angular adjustment of the laser beam in both horizontal and vertical planes making laser alignment a simple one step process The beam steerer speeds up linear angular and straightness measurements whether in line or at 90 The optic is also compatible with the linear angular combination kit and swivel fixed turning mirrors Clamping screws allow the beam steerer to be easily attached to mea2. Improved dynamic response with less than half the weight of BEFOR teel optics housings machine loading is reduced O Quick thermal acclimatisation aluminium optics acclimatise 10 F7 times quicker than steel optics No thermal drift problems the interferometer is remote from the heat of the laser head with the laser heat source remaining outside the machine Q Easier set up the remote interferometer can be fitted to specific 7 areas of interest on a machine without loss of axis travel This also allows for multiple axis measurements to be made from one position ith h ali he without the need to re align the laser With the addition of a linear error compensation package the data obtained from a calibration cycle is used to calculate compensation values which can then be fed into a machine s controller Once the compensation has been completed a final laser check ensures that a machine s positioning accuracy has been significantly improved These packages now include a compensation wizard and session External laser alignment tripod mounted laser makes for easy alignment outside machine Easier long range alignment the larger retro reflector gives an easy target to hit and returns more laser light even in turbulent air Theuniquedesign of linear angular and progress indicator to make axis straightness optics enables easy interchange compensation even easier
