ADC offers the most complete set of ultra-high-precision slits from monochromatic to white beam. 

  • Heidenhain Encoder
  • Cross Roller Bearing
  • Ability to monitor the beam (Optional)
  • Best slit blade edges in the synchrotron community
  • Blade material; Tungsten or Tantalum, Tungsten Carbide, Cadmium, Boron Nitride, or custom
  • Flange-to-Flange Length: 20 to 25 mm
  • Vacuum Level: < 5x10–10 mbar (UHV)
  • Roughness of the jaw edge surface: <0.2µm(rms)
  • Blades can go "past closed" without clashing (Overlapping/Zero beam ~4mm) .
  • Aperture size: 20 mm, 25 mm, 50 mm, & 60 mm
  • Beamline Connection: DN 200, DN 160, DN 100, & DN63
  • Custom configuration is possible, please contact ADC.


All models use cross-roller bearing technology for exceptional straightness of travel.  All of these slits use standard micro stepped stepper motors that could be controlled with a wide array of controllers/drivers available on the market.  Our slits are being used in many synchrotrons around the world (APS, NSLS, ALS, DLS, NSRRC, BESSY, DESY, CHESS, ESRF, BSRF, CAMD, NSRL, PAL, LNLS, CLS, SSRF, IHEP, ANKA, KEK, ASP, SPring-8, ELETTRA, MAXLab, …)


ADC’s slits blade standard deviation for RMS surface roughness for both tungsten and tantalum is less than 0.05 μm.  Please contact ADC for a free copy of 15 page report presenting the data we collected measuring our slits blade surface roughness using Nano fabrication facility at Cornell University.
