Product description

A linear scanner series for all-round fine positioning applications in a cryo-vacuum. Special attention is given to realize a robust mechanism that can tolerate significant handling and payload forces. The central open aperture allows the transfer of fibers, wires or light through the scanner body. The xy-scanner can be simply combined with the z-scanner for motion along all 3 linear axes. The use of non-magnetic materials allows operation in high magnetic fields

* Using a CADM2, -20V to +130V, 10 bits resolution, setpoint rate approx. 10Hz. Alternative: PSM amplifier with PSMIL -20V to +130V.
** Using the PSM without PSMIL, this is only allowed at deep cryogenic temperatures and -150V to +150V is not to be exceeded.

HV rated positioners can realistically be considered compatible with pressures as low as 1E-8 mbar. Lower pressures can be achieved by prolonged baking of positioners in vacuum at 100-150 deg C, depending on the type of positioner. Upon request JPE can provide such service at additional costs.
