Newsletter includes discussion about non-magnetic movement stages for such applications as ion-beam and electron-beam lithography and electron-beam inspection and microscopy
The latest newsletter, 'Inmotion' from Feinmess Dresden is available from its UK representative, Armstrong Optical.
The main news is a discussion about non-magnetic movement stages for such applications as ion-beam and electron-beam lithography and electron-beam inspection and microscopy where residual magnetism in the stages would interfere with the operation of the instrument.
By using linear bearings manufactured from titanium and ceramic balls the residual magnetism can be kept as low as 0.005Gauss (5x10-7Tesla).
Immunity to magnetic fields is not just accomplished by using suitable materials to keep forces low, but also by using electronic components that will operate undisturbed in the high field strengths.
The non-magnetic stages are available as single linear axis, crossed X, Y, rotational and tilt options in a variety of sizes and travel dimension, and are also ready for high vacuum operation.
