Angled water-cooled copper blades (OFHC or Glidcop) with tungsten hard edge defining
Thermally isolated design for maximum thermal stability and minimal drift.
One stepper motor is used to set the slit blade gap and a second motor used to scan
the slits in the beam.
Precision actuator resolution can be controlled to 0.1µm with 5µm repeatability in
open loop, <1µm repeatability when fitted with an encoder.
Slit blade design optimised for specific power requirements of beamline
Our L-aperture slits are ideally suited for high-power applications, with a horizontal
and vertical travel range of ±5mm and sub-µm resolution and repeatability (shown
below). These slits are also suitable for use in a canted undulator geometry as they
can feature an additional bypass aperture.
